BIOLOGY

ANDRES BERMUDEZ, Biology
IMSD Mentor: Kelly Doran, Ph.D.

andres

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.


TESS CONDEFF,
Biology
IMSD Mentor: Stanley Maloy, Ph.D.

TESS

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.

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.

Sean Najjar, poster in hand

Sean Najjar is majoring in Chemistry at San Diego State University and began the IMSD program in January 2016. He is currently working in the laboratory for Dr. Michael Bergdahl on progressive new methods towards the total synthesis of azaspirene, a promising new cancer treatment. Being that of an angiogenesis inhibitor generates the ability to starve tumor cells without the repercussions of denaturing normalized cells, being less detrimental than todays chemotherapy treatment. His help towards the synthesis of azaspirene allows for the potential to supply an ample amount of compound to the advancement in treating cancer by means of a more economical and efficient route. The synthetic approach begins with an easily accessible L-phenyl alanine molecule, which in turns become a chiral source to create the backbone of azaspirene. There are current results showing two-thirds of the synthesis route completed with intentions of finalizing the novel total synthesis of azaspirene and its pseurotin analogs, characterizing the biological activity through active site binding and crystal structure experiments, and evaluating the potential of serving as an anti-inflammatory, anti-angiogenic, and anti-breast tumor agent. Sean plans on pursuing a Ph.D in Organic Chemistry with the intentions of graduating within the year of 2016.

MATHEMATICS

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

Theresa Morrison, IMSD Scholar, presenting research poster

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.
