Took active part in the management of instructional laboratories

HIGHLIGHTS OF ACADEMIC CAREER: Research: Was awarded ~ $2M in external funding (~$1.6M as PI, and ~$1.3M as sole-PI), published 63 peer-reviewed articles, designed and built three functional and continuously funded research laboratories (one for undergraduate research), constantly involved graduate and undergraduate students in experimental work at national facilities.

 From 2006 to 2013 published 31 papers from UTEP in peer-reviewed ISI-listed international journals, the best record among all Associate Professors in the College of Science.

 Paper “Evidence of low-temperature superparamagnetism in Mn3O4 nanoparticle ensembles” and associated story were featured on nanotech.org, sister website of Nanotechnology, the flagship journal of Institute of Publishing (IoP) in Great Britain (http://nanotechweb.org/cws/article/lab/43746).  Was the first at UTEP to be awarded back to back American Chemical Society – Petroleum Research Fund Awards on two different research projects.  Was the first in the College of Science to be awarded back to back grants (for a total of ~ $1M) from the Department of Defense – Army Research Office.  Wrote more than ten research proposals for user access to national synchrotron x-ray and neutron sources in direct competition with Tier One institutions. To date all have been successful and all experiments resulted in journal publications.

Postdoc and Student Mentoring: Supervised three postdoctoral associates, mentored thesis work of 5 Ph.D. and 11 M.S. students; overseen research projects of over 30 undergraduate students (including 3 B.S. theses under the auspices of the MARC program).  Three group alumni (two postdoctoral, one Ph.D.) secured Assistant Professor positions upon completing their studies.  Ph.D. students Heber Martinez and Israel Martinez are both recipients of one of the most prestigious international fellowships awarded by the Mexican Government through CONACyT. The fellowships were awarded through an international competition based on research proposals developed by faculty-student teams.  More than 25 undergraduate students (90% of whom are underrepresented minorities and 50% women) worked on publishable research projects in our Crystal Structure Analysis Undergraduate Laboratory (CSAUL). All these students were either admitted to graduate/professional school or entered the STEM workforce.  Undergraduate and M.S. researcher Antony Adair authored/co-authored five peer- reviewed articles; made the finals of Materials Research Society Meeting Scientific Movie Contest together with a postdoc and a Ph.D. candidate from Harvard, a Ph.D. candidate from Cambridge, and a Ph.D. candidate from the Tokyo Institute of Technology.  Ph.D. recipient Juan Hermosillo secured a permanent position in the oil industry right upon graduation.

Administration: As Chair of the Physics Department, overseen the functioning of a research active department with Physics faculty receiving more than $2.5M in new external funding as PIs during the FY 2014-2015. Coordinated the mentoring of faculty, staff and students, designed and coordinated the enhancement of the department’s instruction and research infrastructure.  Developed strategies to encourage enhancement of research activity in the department, particularly grant proposal submission. Physics faculty secured more than $2.5M in new external funding as PIs during the FY 2014-2015, and more than $2M in new proposals are currently under review by various funding agencies.  Designed, secured internal and external funding, and completed the construction of two new Applied Physics Research Facilities: the Core X-ray Laboratory and the Frontier

Optical Microscopy Laboratory. Both facility are functional. The core X-ray Lab already served more than 50 users including UTEP PIs from two Colleges, postdocs and students. There are more than 20 ongoing research projects in the facility. (http://science.utep.edu/physics/index.php/2014-06-23-14-15-11/research-facilities-2)  Designed, secured internal funding, and coordinated the construction of a new instruction laboratory in Rm. 322. This allowed us to open four new sections of General and Introductory Physics, increasing the overall enrollment in these classes by 220 students in just one semester.  Created position and appointed new Directors of Undergraduate and Graduate Studies  Worked with the Graduate Studies Director to enhance graduation rates at the M.S. level. We graduated 10 M.S. students during the 2014-2015 AY, which currently is one of the top M.S. in Physics graduation rates in Texas (among departments that do not have a Ph.D. program)  Worked with Undergraduate Studies Director to implement a new two-tier advising model and enhance recruitment. This led to doubling the number of Physics freshmen in the Fall of 2014. As Associate Dean for Research in the College of Science, developed new research initiatives and coordinated research activities to increase external funding and improve scholarship within the CoS.  Designed and implemented the first CoS internal funding program, a $140,000 effort to support seed multidisciplinary pilot projects and collaborations aimed at enhancing our scholarship and research resources.  Coordinated the application process for the highly-competitive Texas Higher Education Coordinating Board “Norman Hackerman” Advanced Research Program for early-career faculty and tripled the number of submitted proposals with respect to 2011.  Developed (together with Department Chairs, CoS Dean, and Facilities leadership) a new plan based on centralized electronic communication and specific protocols to enhance the research infrastructure utilization and research support in the CoS
