Current Students: Academic Year 2016-2017
TESS CONDEFF, Biology
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 temporal and spatial changes of stx levels in contamination-affected areas along the San Diego Coast following a rain event. Beaches along San Diego’s coastline are commonly closed after rain due to sewage contamination from Mexico’s Tijuana River and urban runoff from throughout San Diego. The human pathogen, Escherichia coli, carries the phage-encoded shiga toxin gene (stx) and is commonly found in human and animal waste. Phages are viruses of bacteria that can carry virulence genes such as stx. The transfer of toxin genes to bacteria could lead to the evolution of novel human pathogens. With an increased risk of exposure to waste-associated pathogens like E. coli after it rains, it becomes important to monitor impacted environments for phage-encoded toxin genes. 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.

NORHAN ALHAJJAR, Biology
IMSD Mentor: Kelly Doran, Ph.D.
Norhan Alhajjar is a biology major who hopes to pursue a Ph.D. in the field of biology. She joined the IMSD program in July 2016. In the summer of 2015, she participated in the W.M. Keck Scholars program, where she gained experience working in a microbiology lab. During her time in the Keck program, Norhan conducted a research project that involved comparing nitrogen/phosphate levels with the presence of phage-encoded exotoxin genes in beach water throughout the coast of Imperial Beach. The water samples were obtained after a period of heavy rainfall, in which raw sewage was inputted into the Pacific Ocean due to overflow of the Tijuana estuary. The project involved identifying the phage-encoded shiga toxin (stx) and cholera toxin (ctx) genes, which are responsible for the symptoms of some human diseases. Norhan’s experience in the Keck Program initiated her excitement for scientific research and desire to participate in biological research that contributes to public health.
Since fall 2015, Norhan has been working in Dr. Kelly Doran’s lab, whose research primarily focuses on the human pathogen Group B Streptococcus (GBS) and the host-pathogen interactions that take place in the human Central Nervous System and female reproductive tracts. Norhan has been working closely with two graduate students in analyzing the factors that promote GBS colonization of the female reproductive tract. When pregnant women are colonized with GBS, the infant is posed with the serious risk of also being colonized with the bacterium, which may result in the infant developing bacterial meningitis. The current focus of the project is analyzing the role of the BspC protein in GBS, which has been previously well characterized in other Streptococcus species. A further understanding of the host-pathogen interactions between GBS and the reproductive tracts of women is a promising target for the development of therapeutics to prevent GBS infections.

MIGUEL CORREA, Physics
IMSD Mentor: Fridolin Weber, Ph.D.
Miguel Correa is a Physics/Political Science major at SDSU and joined the IMSD program in September 2016. His research is focused in the area of astrophysics and is part of two research groups.
He joined Dr. Fridolin Weber’s group at SDSU in Spring 2016. Dr. Weber’s group investigates the possibility deconfined quarks in neutron stars. A simulation of rotating neutron stars is used to analyze the parameters required to produce a phase transition to quark matter within a star. Miguel currently studies the phenomenon of “twin-peak” stars, stars with same rotational frequencies, but different gravitational masses. These stars form as rotating stars continue to lose energy and angular momentum through magnetic radiation, slightly increasing in rotational frequency as they undergo a phase transition. This study is important as the perceived behavior could be correlated to transitions to quark matter.
After working in the NSF funded Notre Dame REU in 2016, he continued research in Dr. Timothy Beers’ research group. In Dr. Beers’s group, the propagation and properties of iron-deficient or metal-poor stars in the universe are explored. For his summer project, Miguel created and tested new analytical methods to infer carbon abundances from synthetic spectra of warm, metal-poor stars. One of the methods produced promising preliminary results and is being tested further with real spectra. By being able to reliably detect carbon in warm, metal-poor stars, the importance of carbon in the stellar evolution of metal-poor stars can be more easily analyzed.
Miguel is presently the head tutor of the Society of Physics students at SDSU, where he is responsible for managing the undergraduate tutoring services offered by the physics department. His interest in teaching and research has led him to pursue graduate school, with the intention of earning a PhD in theoretical astrophysics and entering academia.
