Welcome to Canada and Montreal for the 2019 International Society for Autism Research Annual Meeting (INSAR 2019). Montreal is a vibrant, multicultural city, making it an ideal venue for such a diverse group of international delegates. Over 2,000 abstracts from all over the world were submitted, reflecting the diversity of research in ASD, from neuroscience and molecular genetics to psychology, medicine, technology, and lived-experience research, to name a few. Congratulations to all awardees, whose research exemplifies the exceptional quality of the research presented at INSAR 2019 this year.

I am grateful to Drs. Joseph Buxbaum and Emily Jones who chaired the scientific program, as well as the members of the newly formed executive program committee, who helped make strategic decisions about engaging new key stakeholders and increasing neuroscience representation in this meeting. Special thanks to the INSAR board for the guidance and support, the many reviewers for their commitment to assure high quality of content, and the committees who were responsible for the special interest groups, awards, luncheons, and much more. My sincere gratitude to Jennifer Gentry of INSAR and Joe Dymek of ConferenceDirect for making this meeting possible, and assuring a smooth experience for diverse delegates.

The 2019 INSAR local community conference is also in Montreal this year. It will highlight both speakers from the INSAR annual meeting, as well as researchers and clinicians from Quebec and their Canadian and international collaborators. Thank you to the many organizations which provided funding for this meeting, my co-chair of the local community conference, Dr Mayada Elsabbagh, for her invaluable insights and support, as well as Dr. Eve-Marie Quintin, and the local advisory board, a diverse group of stakeholders, who advised on content and planning.

We extend a warm welcome to you, and hope you will enjoy a stimulating scientific meeting, have the opportunity to network with your international colleagues, and experience this vibrant city with its unique architecture, exhilarating arts scene, and innovating food experience.

Sincerely,

Evdokia Anagnostou, MD INSAR 2019 Meeting Chair

INSAR 2019 is the Annual Meeting of the International Society for Autism Research (INSAR).

2 SCIENTIFIC PROGRAM

Welcome to the International Society for Autism Research (INSAR) 2019 Annual Meeting in Montréal, Québec, Canada. As your scientific co-program chairs, it has been our privilege to thoughtfully curate the exchange of the latest scientific progress from autism researchers around the world. WELCOME

We hope that you notice that we made a significant commitment to enhance under-represented research disciplines at the meeting. This year, you can expect to see expanded content in biological and medical sciences, and neuroscience more broadly, adding to the already excellent work in psychology and other fields.

To build a robust program, we added additional topic areas for submissions and increased the number of panels and keynote speakers.

High-quality presentations across all key areas of autism research are essential to the success of the meeting. We ensured broad scientific excellence by forming an Executive Scientific Program Committee of senior autism researchers to determine the gaps in science, actively solicit keynotes and panel participants in these areas, and provide final review for top panels and oral sessions.

We also launched an initiative to ensure that panel proposals, while continuing to address cutting edge themes in autism research, also reflect a diversity of viewpoints and/or approaches, as well as diversity in other domains, including gender, geography, ethnicity and career stage.

The updates to the expanded call for abstracts were well received by scientists, which was proven by the over 2,000 submissions we received this year. After a strenuous review process, over 1,800 posters, oral and panels were accepted that will represent research from over 50 countries across the globe.

Our keynote speakers, Kathryn Roeder, Jason Lerch, Elizabeth Berry-Kravis and Vikram Patel, will enrich the meeting by offering their knowledge on genetics, neuroimaging, neurobiology, clinical trials and global health in autism and associated disorders.

We are grateful to the members of the INSAR Board, Executive Scientific Program Committee and Jennifer Gentry, INSAR Administrative Director, for their hard work and perseverance as we worked through the growing pains of expanding the science represented at the meeting and restructuring the review process.

It was a great honor to help organize the scientific program that presents the latest research and findings in the field of autism and hope our inclusion of diverse research ensures that INSAR remains the single place to go for information about autism advances.

We hope you take advantage of the opportunity to meet and brainstorm with your colleagues and bring new ideas home with you that will inspire new research to improve the quality of lives for people with autism and their families.

3 PRESIDENT’S WELCOME

It is my pleasure to welcome you to Montreal for the 2019 Annual Meeting of the International Society for Autism Research (INSAR). The INSAR Annual Meeting is the only conference worldwide that brings together thousands of scientists who study autism from a range of disciplines, alongside policy makers, practitioners, autistic people and their families, to learn about latest research, share new ideas, and strengthen or create new collaborations. I hope you have a wonderful few days, and you leave inspired by what you learn and with a sense of how we are all working together to improve the lives of autistic people, through better understanding. I would like to thank the 2019 Meeting Chair, Evdokia Anagnostou, who in addition to the responsibility of the logistics of the Annual Meeting is responsible for putting together the terrific INSAR local community conference held prior to INSAR 2019. She and the local community conference co-chair, Mayada Elsabbagh, worked with a diverse group of stakeholders and a local advisory board on content for the event. Evdokia worked closely with Joe Dymek from Conference Direct on the logistics of the INSAR 2019 meeting. Behind the scenes, the INSAR Office went through some major transitions over the last year. I am particularly grateful to Jennifer Gentry and Jennifer Crane from Crane Martin for handling the urgent transition from our former association management company so smoothly, when the last company announced they were closing. I am also very grateful to Professor Joe Buxbaum and Dr. Emily Jones who took responsibility for the outstanding scientific program. They worked with the Executive Scientific Program Committee who coordinated the scientific reviews of hundreds of abstracts and proposals. We have ended up with an impressive line up of keynote speakers, panels and scientific sessions showcasing cutting edge autism research. In particular, in response to feedback from recent annual meeting attendees, Joe and the Executive Committee have worked hard to restore the balance between biological and non- biological science in the content of the program. To understand autism and help autistic people we need both sides of the research while maintaining a level of scientific excellence in presentations. Once again at the Annual Meeting we also have many Special Interest Groups (SIGs), international collaborative meetings, student and trainee activities, cultural diversity activities and early career events. These ensure we are fostering the next generation of autism researchers and anticipating important emerging themes in autism research. This year’s INSAR Lifetime Achievement Award goes to Professor Cathy Lord who has made seminal contributions to the assessment and diagnosis of autism, over many decades. We look forward to hearing her acceptance speech. I am also delighted that the INSAR Advocate Award will this year be given to Debbie Hilibrand, who has worked in the National Alliance for Autism Research and in the Hilibrand Foundation. She has been a strong advocate for the autism community and succeeded in increasing funding for research. The Cultural Diversity Research Award recognizes research with significant impact on culturally diverse and underserved communities. It particularly celebrates investigators who conduct community-based or community-partnered research. The 2019 Cultural Diversity Research Award will go to Cecilia Montiel-Nava. This year the Slifka-Ritvo Innovation in Autism Award has been awarded to Sarah Cassidy. Please join us at the Awards Ceremony on Thursday afternoon to hear about all of these Awardees, and to also celebrate our Young Investigator Awardees, and Dissertation Award winners, the young scientists who will be leading their own labs as PIs in the future. INSAR depends on its Board who meet once a month by conference call to make collective decisions about how INSAR can achieve its mission and strategic priorities. The INSAR Board (listed on page 20) works closely with many committee chairs and members to advance our mission. All the Board members and committees contributed to organizing this Annual Meeting. All of these people work in a voluntary capacity because we care passionately about advancing autism research and improving the lives of autistic people and their families.

4 PRESIDENT’S WELCOME

Peter Mundy, President-Elect, has also been a terrific new addition to the Board this past year and will take over from me as President at the close of the Annual Meeting. Your newly elected officers for Secretary, Treasurer and Vice-President will also be announced at the Business Meeting on Saturday. I have had fantastic support from these colleagues and I pay tribute to Geri Dawson and the long line of previous Past-Presidents who have left INSAR in such a strong position. Geri introduced the INSAR Policy Briefs (the first addressed Autism and Employment and the second is addressing Autism and Suicidality). She also introduced the award of INSAR Fellows, the newest cohort of whom will be honored on Saturday at the Business Meeting. Please come along to applaud them. As President, I have introduced some additional initiatives. The first is to ensure we have an autistic person representing autistic people on the Board, and John Elder Robison has been a wonderful colleague in this role. The second is to increase INSAR’s international reach. The INSAR Annual Meeting rotation has been to meet outside of North America once every 5 years. Since our meetings outside North America have been well attended and not a financial burden on the Society, the Board made a strategic decision to change our pattern to every 3 years. This is in addition to our Regional Meeting that this year will be in Chile. Finally, I have introduced the new role of INSAR Global Senior Representatives, with the aim of identifying a senior person in every country around the world who can keep INSAR informed of developments in their country, who can act as a focus for autism researchers in their country, and who can join together once a year to see how we can work together across national borders for the benefit of autistic people and their families. This new initiative is in the initial planning phase but details will be coming over the next year as this is further developed. Please let me know your ideas of what else INSAR can and should be doing, by emailing me at [email protected], or chatting with me during coffee. Enjoy INSAR 2019, catching up with old friends and making new ones, listening to exciting research presentations and debating the science, what it means, and how we can ensure the science leads to better support for autistic people and their families. Thank you for contributing to INSAR by being a part of this exciting meeting. Kind regards,

Simon Baron-Cohen, FBA, FMedSci INSAR President

Jason joined WIN in March of 2019; prior to that he completed his Ph.D. in 2005 in the Department of Neurology and Neurosurgery at McGill University and a post-doctoral fellowship at MICe from 2005-2008 with Dr. Mark Henkelman and Dr. John Sled. He received his B.A. in 1999 in Anthropology and Social Studies of Medicine from McGill University. His Ph.D. research, under the supervision of Dr. Alan Evans, was on in-vivo measurements of cortical thickness from MRI. His current research focus is on detecting neuroanatomical changes due to behavioural and genetic manipulations in tightly controlled mouse models, primarily related to neurodevelopmental disorders, and to relate these findings to sadly not so well controlled human subjects. As an antidote to these academic pursuits, he likes to leave the city and hike in the woods, whenever possible.

Understanding Heterogeneity in Autism Research and Clinical Practice: A Multidisciplinary Approach

This is a six-week webinar series (occuring on Thursdays from 13th June to 25th July) focused on broadening our understanding of the co-occurring psychiatric, medical, and developmental conditions of autism through empirical research, and implications for inclusive clinical practice and tailored support towards individual needs.

Each presentation will address heterogeneity within autism through diverse topics including: psychiatric, biomedical, developmental, and gender identity issues in autism. Presentations will be followed by Q&A with the expert presenter(s).

Speakers include: Jeremy Veenstra-VanderWeele, Julie Lounds Taylor with Somer Bishop, Shafali Jeste, Jeroen Dewinter with Anna Van Der Miesen, Emily Kuschner, Conor Kerns with Roma Vasa.

Seminars are designed for students, post-doctoral fellows, early-career investigators, families, service providers and people with autism and their families. Anyone is welcome to attend.

Although forging definitive links between is challenging, genetic alterations and behavioral impairments it is not insur- mountable task. Translational including endpoints, behavioral outcomes, are essential for studying mechanisms of neurodevelopmental and disorders developing strategies. And while not all behaviors and therapeutic treatment clinically reliable, or phenotypes studied in the laboratory are robust, relevant, enabling translational there are many that are prime and valuable for experi- ments. Our proposed symposium will highlight four speakers whose research highlights robust and reliable behavioral and physiological outcome mea- sures and innovative that can be assessed parameters in both humans and animals. Our speakers will discuss optimizing what behavioral data can tell us and what it cannot, and how to be cautious consumers of behavioral data. We will discuss how multiple domains of behavioral phenotypes and cross species studies could/should be embraced to improve translational efforts. We will also demonstrate how pairing behavior with a physiological marker can corroborate and expand translational research and how these innovative measures can facilitate studies and better predict clinical success for ASD and neurodevelopmental disorders. 3:30 3:55 4:20 4:45 2:54

A. Laugeson, Semel Institute for Neuroscience and Human Behavior, UCLA, Los Angeles, CA Social skills Training (SST) is a widely used intervention technique in autism practice. Latest research has consistently shown moderate effects in large randomized controlled trials. Still, a multitude of questions remain around SST’s effectiveness and efficiency. In addition, self-advocates have been critical of SST. This session provides both a state-of-the-art overview of SST, and insights into the latest developments in addressing challenges and the unknowns of SST in autism. We present new research findings and discuss issues of personalization of SST, its generalization, and cross-cultural valid- ity, as well as the need to redefine outcomes, and optimize administration and dosage.

This year’s INSAR policy brief thus identified the top 10 research and policy priorities to prevent suicide in autism, in partnership with autistic people and their allies. This panel will discuss the findings and implications of this policy brief, in the context of current international suicide in autism research. First, a reflection from a lived experience perspective on the policy brief find- ings, and importance of researchers working in partnership with autistic people and their allies to decide priorities which will affect their lives. Second, the latest international research findings in relation to effectively understanding, identifying and managing risk of self-harm and suicide in autistic people will be discussed.

In this panel, presentations will examine the cultural (e.g., language, values) and structural (e.g., therapy services, health insurance) factors that affect access to diagnosis and services among Latino, African-American, and Korean-American children/youth with ASD in the United States. This panel will characterize how families from diverse racial/ethnic cultures navigate structural systems and provide recommenda- tions on steps to address disparities from infancy to young adulthood. This research will inform global approaches in minimizing disparities affecting individuals with ASD worldwide.

Girls may have important socio-communicative strengths that “camouflage” their challenges and deficits related to ASD, which in turn placesfor under-diagnosis, them at risk delays in diagnosis, and a growing sense among both reduced access to treatment. Although there is researchers and self-advocates that autism may be camouflaged in girls, there is not yet a clearly established set of diagnostic differences by sex, neces- sitating further research in this area. The presentations in this panel will focus on differences by sex among autistic youth in performance on standard diag- nostic tools used in research in and clinical practice for identifying and ASD co-occurring conditions, as well as associated disparities in access to care. of emotional- and related areas Sex differences in both core domains of ASD behavioral functioning Data from the National Survey on will be explored. Children’s Health will also examine disparities in psychotropic medication prescription rates as possibly related to differences in clinical conceptualization of co-occurring conditions. 1:30 1:55 , , 5 2 , (1) 1,6 , P.
