Current Students: Academic Year 2015-2016


IMSD Mentor: Kelly Doran, Ph.D.


Andres Bermudez is a fourth-year Biology major and was accepted into the IMSD program in the spring of 2013. He is currently working in the lab of Dr. Kelly Doran, who studies the mechanism by which Group B Streptococcus (GBS) penetrates the blood-brain barrier to cause meningitis. Meningitis is a severe infection of the central nervous system (CNS) and a leading cause of mortality among newborns. Andres’ project focuses on identifying a bacterial factor responsible for causing a disruption in tight junction expression of the specialized endothelial cells that make up the blood-brain barrier (BBB). Tight junction protein complexes maintain BBB structure and function and are crucial for preventing pathogens from accessing our CNS. Better understanding of GBS pathogenesis could lead to the development of therapeutic intervention. Andres is currently in the process of applying for summer research programs and is expected to graduate in May 2016. He also intends on continuing his education towards a Ph.D. in neuroscience so that he may one day be involved with research on Alzheimer’s disease.

IMSD Mentor: Stanley Maloy, Ph.D.


Tess Condeff is a Biology major who joined the IMSD program in May 2015. She conducts research in Dr. Stanley Maloy’s lab where they investigate the effect the transfer of phage-encoded genes has on the evolution of novel pathogens in the environment. Tess’ project investigates the presence of phage-encoded exotoxin genes along the San Diego coast during and after a major rain event. Following a period of heavy rain, a great deal of waste from San Diego County runs off into the Pacific Ocean. Currently, waterway contamination is monitored by cultivation of fecal coliform indicator bacteria. This current method is timely and does not test for any viruses that may be present in the water. Ultimately, Tess’s project aims to develop a molecular test that can be used to more accurately and rapidly test for pathogen presence in recreational waterways. Tess is expected to graduate in May 2016 and is currently applying to graduate programs with the ultimate goal of obtaining a PhD in Biomedical Science.

Dr. Christopher Harrison identified him as a top performer in his Analytical Chemistry course and invited Adam to work in his lab upon completion of the course. Their research addresses the use of performance enhancing drugs and the need for a quick, cost effective, and reliable method to analyze blood samples. The research has reinforced Adam’s resourcefulness and patience by optimizing his electricity capacitance detector to analyze solutions through electrophoresis.  Adam also tutors mathematics and chemistry for San Diego State University, Grossmont Community College, and his local community.


ARIANNA AYONON, Chemistry (emphasis in Biochemistry)
IMSD Mentor: Jeffrey Gustafson, Ph.D.

IMSD Scholar, Arianna Ayonon, in chemistry lab

Arianna is currently a Senior majoring in Chemistry with Emphasis in Biochemistry who joined the MBRS/IMSD program in June 2015. Her passion for organic chemistry led her to joining Dr. Jeffrey Gustafson’s group where she currently conducts research on the synthesis of atropisomerically preorganized analogs. Atropisomerism arises from chirality about a hindered axis and as a result produces a pair of  enantiomers that are rotational isomers of each other. By hindering or “preorganizing” this axis, isomers can be locked in their respective conformations where this stereoselectivity has a potential in drug discovery. She currently works on α-Helix Mimetics but is ambitious to assist in the group’s related projects. Arianna is also an active member of the American Chemical Society Student Chapter where she also serves as a tutor for organic chemistry courses. She hopes to pursue a Ph.D in Organic Chemistry and plans on graduating in Fall 2016.


CARLOS BRAMBILA, Bioengineering
IMSD Mentor: Paul Paolini, Ph.D.


Carlos joined the IMSD program in July of 2013 as an undergraduate in Biology with an emphasis in Bioengineering. Carlos joined Dr. Paul Paolini’s laboratory in the fall of 2012 through the NSF S-STEM program, and is currently conducting his research project in the Paolini laboratory. Dr. Paolini’s laboratory focuses on the mechanics and dynamics of the neonatal rat cardiocyte to further understand the human heart. In the Spring of 2013, Carlos had the opportunity to presented his first research poster at San Diego State University’s Student Research Symposium. The following year in February, he co-presented his current research at the Biophysical Society Meeting in San Francisco, which focuses on creating an open-source, cost effective stimulator to study the comparison of cardiocyte cultures between paced and unpaced cells in order to observe changes in gene and protein expression of myosin isoforms over time. In the summer of 2014, he was accepted in the National Nanotechnology Infrastructure Network (NNIN) Research Experience for Undergraduates program and conducted research at the Harvard School of Engineering and Applied Science under the project title “High-Throughput Drug Screening in vivo Using Droplet Microfluidics” where he presented his work at various conferences in Atlanta, Georgia, Los Angeles, California, and San Antonio, Texas. Carlos is very interested in the application of Bioengineering aspects in his current project at SDSU and plans to focus his research in the field of biomaterials, tissue engineering, and/or biomedical instrumentation. His primary academic goal is to obtain his doctoral degree in Bioengineering or Biomedical Engineering and have a laboratory of his own at a university where students will have the same opportunities as he did: to unfold their passion and potential in the sciences.


EVAN TULLY, Bioengineering
IMSD Mentor: Sanford Bernstein, Ph.D.


Evan Tully is a Bio-engineering student and began the MBRS/IMSD program in September 2014. He is currently working in Dr. Sanford Bernstein’s Drosophila Lab. He just began working on his own research project, which focuses on analyzing the the human genetic defect, Myosin Storage Myopathy (MSM). This disease is myogenic and affects the way myosin is formed and stored in the human body. It will be his job to analyze and characterise the effects of the disease based on the functionality of the fruit flies whose genome has been introduced to MSM. The implications for research of this kind are vast, but serious breakthroughs in the field are present.


KAREN KEY, Psychology, minor in Social Work
IMSD Mentor: Allison Vaughn, Ph.D.


Karen D. Key is a Psychology major with a minor in Social Work and began the IMSD program in June 2015. She is working in Dr. Vaughn’s Social Relationship and Health lab since January 2014. Dr. Vaughn’s lab focuses on social relationships, mental and physical health, and stereotypes of sexual minorities. In February 2015, she had the opportunity to co-present her first research poster at the annual Society for Personality and Social Psychology (SPSP) convention, where she received the SPSP Diversity Fund Travel Award for Undergraduates. This poster focused on resource effects on in-group boundary formation with regard to sexual identity. In March 2015, she presented her recent research at the San Diego State University’s Student Research Symposium and in May 2015, she co-presented an oral paper as part of a larger symposium at the annual Western Psychology Association convention, which focused on causal attributions towards mental and physical stigmas. Currently, Karen is working on a senior project where she is investigating the effects of perspectives (either individual or social) on affective responses and behavioral intentions towards stigmatized individuals. The results will provide a more thorough understanding of the stigmatization process taking into account the importance of perspective. Understanding these two perspectives will provide an integrated social model that is a necessary step towards breaking down the stigmatization process. With hopes of reducing stigmatization towards individuals with mental and physical disabilities, Karen looks forward to pursuing a doctorate in psychology. Through her involvement in different activities, Karen aspires to become a university professor – conducting research and mentoring diverse students. Karen will be graduating in May of 2016 and will be applying to doctoral programs in Fall of 2015.

SHANNON YANDALL, Psychology, minor in Biology and Interdisciplinary Studies
IMSD Mentor: Paul Gilbert, Ph.D.


Shannon Yandall is a Psychology major with minors in Biology and Interdisciplinary Studies. She is a second semester transfer student from San Diego Mesa College and began the MBRS/IMSD Program in February of 2015. She is currently conducting research at the Center for Healthy Aging and Neurodegenerative Disease under the guidance of Dr. Gilbert. She is studying the changes that occur in the memory of older adults, specifically the relationship between spatial memory and pattern separation. Shannon helps administer the battery of neuropsychological tests to both elderly and young participants, as well as score, enter, analyze and interpret the data. She will be presenting this research at SDSU’s upcoming Student Research Symposium Event.

Prior to coming to SDSU, she was an active member of Psi Beta, the community college honor society for Psychology students, holding the secretary position for two semesters. During this time, she also helped conduct research at the San Diego Zoo with the mandrill species. Shannon observed and collected pictorial and social interaction data to study the relationship between coloration changes in the perineal area of female mandrills and their social interaction with the alpha male mandrill. Since mandrills are an endangered species, this research is helpful to the zoo in their efforts to initiate reproduction of the four mandrills housed there. She will be presenting this research at the upcoming Western Psychological Association Convention this Spring. She graduated from San Diego Mesa College with an Associate of Arts with Honors.

Since transferring to SDSU, Shannon has exemplified terrific leadership skills on campus.

THERESA MORRISON, Applied Math, minor in Physics
IMSD Mentor: Christopher Curtis, Ph.D.


Theresa Morrison is a senior Applied Mathematics student with a minor in physics and began the IMSD program in April 2015. She is currently working with Dr. Christopher Curtis in the Department of Mathematics on analysing the dynamics of the surface evolution of bilinear shear flows. Inparticular she is studying the surface and internal layers and the creation of nonlinear waves. This work is an important fluid dynamics question because it has an additional layer of complexity because the fluid we are studying has a constant vorticity. This allows our model to better approximate the true dynamics of fluid layers in more complicated systems such as the ocean. This work is going to presented at the Joint Mathematics Meeting in January 2016.

In the 2013-2014 academic year Theresa also worked on a project with Dr. Peter Salamon and Dr. Rebecca Theilmann on the movement of mucus within the lungs with Cystic Fibrosis. This work was peresented at the SDSU SRS in the spring of 2014. In the summer of 2014 Theresa had the opportunity to work at Fairfield University with Dr. Shanon Reckinger studying oceanic overflows. This work was presented at the American Physical Society- Division of Fluid Dynamics and the Joint Mathematical Meeting where she earned the outstanding poster award. In the summer of 2015 Theresa worked at UC Merced with Dr. François Blanchette and Dr. Mayya Tokman studying the use of exponential time integrators in simulating fluid flows.
