The Science Center Administrative Team is dedicated to science education at Brown and beyond.  Feel free to contact us with questions regarding our programs and initiatives.


 Gelonia L. Dent, PhD, a graduate of Brown’s Division of Applied Mathematics (PhD '99, MSc '97 Engineering), is the Director of the Science Center.  She earned a M.S. in Mathematics at Clark Atlanta University, and the B.S. in Mathematics at the University of Georgia at Athens. Dr. Dent is a patented and published researcher for her work modeling the dynamics of physical systems at IBM’s TJ Watson Research Center. She managed Scientific Computing at the American Museum of Natural History, served on the faculty in the School of Engineering at North Carolina A&T State University, and served as Assistant Professor in the Department of Mathematics at Medgar Evers College of the City University of New York. 

  As the Science Center Director, she manages and provides strategic leadership to the Science Center’s mission to support and promote STEM learning and communication campus wide, as well as its goal to improve and expand the Center’s diversity initiatives: The New Scientist/Catalyst (NSP) Program, Women in Science and Engineering (WiSE) Program, and Science and the Arts (STEAM). “The ability to connect students and faculty who possess in-depth knowledge of their academic discipline and cultural capital (i.e., the non-monetary assets- formal education, intellect, knowledge, skills, attitude, style of speech, dress, or physical appearance that a person possesses, which confer advantage and promote social mobility) to the larger community of scientists are key elements of successful support programs targeted at increasing and retaining students in the STEM disciplines.” - Dr. Dent

David Targan, PhD is Associate Dean of the College for Science and an Adjunct Associate Professor of Physics.  Dean Targan received degrees from Brown (Sc.B.), University of California-Los Angeles (M.A.), and the University of Minnesota (Ph.D.). While at UCLA and Minnesota, he conducted research on cataclysmic binary stars at Lick Observatory, Mt. Lemmon, and Palomar. Dean Targan is a member of Brown's Department of Physics and, as Director of the Ladd Observatory, oversees public programming and special programs in which area teachers and students conduct original research in astronomy using Brown's supercomputer and telescopes.

            As Associate Dean for Science Education, David Targan has helped build nationally recognized science programs, such as the Women in Science and Engineering (WiSE) program and the Sloan-sponsored science faculty workshop. He is currently spearheading initiatives on public access to science, informal science education, computational astronomy, and medical education. He also serves as co-Principal Investigator on Brown's National Science Foundation GK-12 grant, the NASA Space Grant, and other federally and privately supported science programs. Contact Dean Targan for consultation and advising about any issue related to the physical sciences at Brown.

Oludurotimi Adetunji, PhD is Associate Dean of the College for Undergraduate Research and Inclusive Science and an Adjunct Assistant Professor of Physics.  Dr. Adetunji earned a B.S. in Physics and Computer Science from Fisk University and the Ph.D. in experimental condensed matter physics from The Ohio State University. During his tenure at Ohio State, Dean Adetunji worked as a Physical Scientist in the areas of biomaterials and nano-channel glass device/applications, at the Naval Research Laboratory in Washington, D.C. He also conducted research focused on the development of piezoresistive sensor based on nano-network of conducting polymers. As the Assistant Dean for Natural and Mathematical Sciences at The Ohio State University, he received two National Science Foundation grants, including one leading to the development of an intervention model for inspiring future geoscientists.  

A member of Brown’s Department of Physics and the leadership team of the Center, Dean Adetunji brings his interdisciplinary Science, Technology, Engineering and Mathematics research background and experience to his current interest in STEM education. He is developing new innovative approaches to STEM teaching, learning and communication through narratives and multimedia platforms.

  As Associate Dean for Undergraduate Research and Inclusive Science, Dean Adetunji oversees the Undergraduate Teaching and Research Award (UTRA) Program, Broader Impacts and STEM initiatives in several areas including the Science Cartoons (Sci-Toons) production program, Brown Science Prep (BSP), Learning Exchange (LE) and program assessment. In addition, he leads the STEM Outreach office and chairs the Brown’s Broader Impacts Committee.

Geeta Chougule is the Sigma Xi Brown Chapter Program/AAU Administrative Aide School of Engineering.Geeta received her B.S in Electrical Engineering from the University of Colorado.

  She supports the Associate Dean of Science Education in the goals of the Sigma Xi program at Brown, and with the Brown Tougaloo Partnership (BTP), to boost membership into the honor society and create events for students who qualify for nomination. She also supports the director’s mission for work related to the AAU grant. Geeta worked on the HHMI grant to help the director with the Catalyst 2015 program. She helps the Dean administratively in various duties.

  Prior to joining Brown, Geeta was with Harvard Medical School where she managed the New England Science Symposium. Geeta is the mother of two boys who grew up in New England and went on to colleges in the area. She returned to work after taking a leave of absence to stay at home to raise her children. Geeta finds working with bright undergraduate science students exciting and uplifting.

Kyle Trenshaw is the STEM Education Postdoctoral Research Associate Kyle received his B.S. in Chemical Engineering from the University of Missouri - Columbia in 2009. While earning his B.S., he served as both a teaching and a research assistant. His positive experience in those positions informed his decision to apply for graduate study. After graduation, Kyle started his graduate work at the University of Illinois at Urbana-Champaign. He received his M.S. in Chemical Engineering in 2011 with a thesis focusing on engineering biological systems for tunable gene expression. During his M.S. thesis work, he was awarded the Chemistry-Biology Interface Training Program Fellowship that prohibited him from teaching for the duration. He found himself missing the teaching aspect of his graduate work and the experience made him rethink his true passions in engineering. Consequently, he adjusted his focus for his Ph.D. thesis toward engineering education. He successfully defended and deposited his Ph.D. dissertation focused on improving students' affective outcomes in core engineering courses using student teams in 2013.

  Since Kyle's defense, he has moved to Providence and joined the staff at the Science Center as the STEM Education Postdoctoral Research Associate. His work at the Center focuses on improving undergraduate science, technology, engineering, and mathematics (STEM) education at Brown University with a specific motivation of increasing students' mathematics competency in STEM courses. He also has a personal research interest in the experiences of lesbian, gay, bisexual, transgender, and queer (LGBTQ+) students in STEM fields and hopes to promote LGBTQ+ supportive practices in higher education with his future work.
