Rey joined the MBRS program in January 2012 as a biology major with an emphasis in zoology, and currently works in the Laboratory of Animal Behavior and Conservation with Dr. Rulon Clark. The Clark Lab focuses on squamate and small mammal ecology, and Rey’s current area of investigation focuses on levels of activation and sustainment of sympathetic nervous system arousal in California ground squirrels (Spermophilus beecheyi) in response to in situ presentations of various visual and olfactory stimuli; including live tethered snakes, snake models, and novel, decontextualized objects. Rey’s goal is to obtain his Ph.D. and continue his research in the hopes of augmenting the current understanding of the modular, rattlesnake-ground squirrel predator-prey system, and apply its usage as a model for analyzing the physiological and behavioral consequences of predator recognition and deterrence in natural ecological systems. Aside from wildlife biology, Rey enjoys playing guitar and performing with his band at musical venues throughout San Diego. He will graduate from San Diego State University with his B.S. in Zoology and will begin applying for Ph.D. programs in Fall 2013.
ERIKA GARCIA, Biology/Zoology
MBRS Mentor: Marshal Hedin, Ph.D.
Erika joined the MBRS/IMSD program in February 2012 as a Biology with an emphasis in Zoology major. Her research experience began in the summer of 2011 as a Ronald E. McNair scholar in collaboration with postdoctoral student, Axel Schönhofer, Ph.D. in Dr. Marshal Hedin’s lab. The Hedin lab focuses on arachnid evolution, systematics, and conservation with particular emphasis on mygalomorph (e.g. trap-door spiders, tarantulas, and kin) spiders and Harvestmen (Opiliones). Erika’s current research with Harvestmen aims to discover cryptic diversity in the Family Phalangodidae, more specifically within the genus Bishopella. The genus of Bishopella currently includes three described species, but studies indicate that this taxon includes many (at least 11) well-supported, genetically divergent lineages, perhaps representing distinct species. Using Next-Generation Sequencing (NGS) Technology and the Exon-Primed Intron-Crossing (EPIC) research approach, the main goal is to identify molecular markers that can specifically enable to resolve shallow phylogenetic divergence within Bishopella. Erika’s goal is to obtain a Ph.D. in the Zoological sciences, particularly focusing on terrestrial arthropod biology. She aspires to contribute significantly to the scientific field with the intention of spreading awareness of the importance of conserving animal habitats and biological diversity.
Efren joined the MBRS program in December 2012. He is a biology major with an honors minor in interdisciplinary studies and conducts research in the laboratory of Dr. Kelly Doran, where the main interest is bacterial pathogens associated with Central Nervous System disease. Specifically, the Doran Lab focuses on the mechanisms by which bacteria penetrate the blood brain barrier to cause meningitis and seeks to identify gene and gene products associated with cellular invasion and characterize host innate immune response to infection. Efren’s project seeks to examine the effect of Group B streptococcus infection on the expression and distribution of the ZO-1 protein, the primary regulatory protein of tight junction formation in the BBB, as well as identify important bacterial factors responsible for BBB breakdown. Efren will apply to PhD programs in Fall 2013 and hopes to work at an academic institution, where he will be able to combine his passions for research and mentoring.
Alicia joined the MBRS IMSD program in April 2012. She is fascinated by the human brain and is double-majoring in psychology and biology. She is currently conducting research in the laboratory of Dr. Ralph Feuer. This laboratory is interested in looking at the effects that a previous coxsackievirus infection can have on the central nervous system of the host that survives it. Her project is specifically looking at a transgenic mouse model for Alzheimer’s disease to determine if a persistent infection can alter the course of this disease. The purpose of this project is to gain insight on the interaction between enteroviruses and neurodegenerative diseases. Thanks to the help of this program and her mentor, Alicia has been able to present her research at a national conference and on campus on multiple occasions. Since she joined the program, she has been recognized with a scholarship, a research scholar award and a presentation award. Alicia will be applying for Summer research programs this Spring to expand her research experience. In the future, she wants to obtain a Ph.D. in Neuroscience to apply her knowledge in biology and psychology and to further research on neurological diseases from an interdisciplinary perspective. Her ultimate goal is to become a university professor and inspire students to learn about the human brain. Summer 2013 Research: MIT Summer Research Program in Biology and Neuroscience
JERRELL TISNADO, Biochemistry
MBRS Mentor: Carl Carrano, Ph.D
Jerrell joined the MBRS program in May 2012 as a chemistry major with an emphasis in biochemistry. His adolescent-age interest in the sciences came from his affinity for the traditional white lab coat—and to this day he thinks it looks pretty cool. Jerrell developed a deeper appreciation for the sciences over time, particularly during his junior year as an undergraduate intern at Prometheus Labs, a biotechnology company, where Jerrell entered into his first research position. Here he participated in cancer research focused on further developing proprietary cancer diagnostics instrumentation aimed at identifying various cancer cell phenotypes. Jerrell’s work at Prometheus earned him a competitive scholarship from the Biotech Employee Development Coalition (BEDC) who recognize and support San Diego County students who have demonstrated academic and workplace excellence. Currently, Jerrell is continuing to build his research experience at SDSU in a bioinorganic laboratory with Dr. Carl Carrano, Chair of chemistry department. This project is investigating the effects that an increasingly acidic ocean has upon the iron uptake (and storage and control) by a variety of algal-associated marine bacteria. Insight regarding this interaction is important given the critical role that iron plays as an essential marine micronutrient at all trophic levels. Jerrell intends to graduate from SDSU with a B.S. in BioChemistry with ACS certification and will begin applying for Ph.D. programs in Fall 2013. Summer 2013 Research: Harvard University

ROSANNAE CHHOUK, Environmental Science and Sociology
MBRS Mentor: Richard Gersberg, Ph.D.
Rosannae Chhouk is a Sociology and Environmental Science major and began the MBRS/IMSD program in September 2011. She is currently working in the laboratory of Dr. Richard Gersberg in the Department of Public Health on measuring pyrethroids, particular bifenthrin and permethrin, in collected stream sediment samples. Understanding this pesticide is critical. They are known to be toxic to non-target invertebrates, like zooplankton, that are beneficial to our environment. To separate the pyrethroids from the sediment, ultrasonificaiton and microwave extraction techniques were used. Samples were processed using the liquid chromatography coupled to a quadrupole mass spectrometer (LC-MS/MS). Parameters were manipulated to promote accurate pyrethroid detection. In summer 2012, Rosannae was granted another excellent opportunity to research aquatic ecosystems at Woods Hole Oceanographic Institution (WHOI) as a summer fellow in the Summer Student Fellowship program. At WHO Rosannae worked in the Biology Department in Dr. Donald Anderson’s laboratory and under the direct mentorship of Dr. Michael Brosnahan and Dr. Katherine Hubbard. Her project focused on how advances in remote sensing shape our understanding of harmful algae blooms, particularly through two new developments: the imaging flow cytobot (IFCB) and the environmental sample processor (ESP). Harmful algae blooms (HABs) describe the proliferation of toxic phytoplankton and microalgae that adversely affect our natural resources and public health. Over 12 weeks, she explored how the ESP and IFCB can be used to detect cellular abundance and predict the growth rate of Pseudo-nitzschia seriata and Alexandrium tamarense respectively.
