CARLOS ALVAREZ, Biology
IMSD Mentor: Paul Paolini, Ph.D.

Carlos Alvarez is a Biology major with an emphasis in Cell and Molecular Biology. He began the MBRS/IMSD program in November 2014.  He is currently working in the laboratory of Dr. Paul Paolini in the Department of Biology measuring the variation in calcium regulation in different regions of cardiomyocytes. Calcium inflow/outflow is tightly regulated in order to induce a rhythmic contraction and relaxation of cardiomyoctes. Improper regulation of this signal molecule could lead to arrhythmia, tissue damage and other heart complications. Understanding how calcium is regulated could lead to the development of treatments for heart disease and drug discovery.

Carlos is also working in Dr. Joy Phillips and Dr.Marilyn Thoman’s lab in the Donald P. Shiley Bioscience Center, studying the immune cell population of the lung pleural cavity, and assessing the effects of fetal alcohol syndrome on the immune system regulatory mechanisms.

In the summer of 2012, Carlos was selected for a summer internship at The Scripps Research Institute (TSRI). At TSRI, Carlos worked in the Immunology Department under the direct mentorship of  Dr. Ann Feeney. His project investigated the effects of the growth factor IL-7 on germ line transcription during pro B to pre B cell stages of cell development.This provided further insight into the regulatory mechanisms in place during B cell generation. Understanding the regulatory mechanisms involved in immune cell generation can be applied towards remediating immune deficiencies and the epigenetic modifications associated with immune disorders.

In the summer of 2014, Carlos was selected for an internship at the University of Utah. During his stay he was able to work under the mentorship of Dr. Dean Tantin, in the Pathology Department. His project investigated the interaction of Oct1 transcription factor and OcaB co-activator, and their recruitment of Jmjd1a, a histone demethylase, during the generation of memory T cells. The absence of this interaction prevents the generation of an efficient memory response when re-exposed to an antigen. The study of fundamental mechanisms of the adaptive immune system can potentially lead to the generation of vaccines and the remediation of immune deficiencies, as well as development for treatment therapies for reestablishment of proper immune response.

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.

BEN TURNER, Cellular & Molecular Biology
IMSD Mentor: Elizabeth Dinsdale, Ph.D.

Cristo Redentor (1)
Benjamin Turner is a senior majoring in Cell & Molecular biology working in Dr. Elizabeth Dinsdale’s metagenomics and microbial ecology research laboratory in the Department of Biology. Currently he studies how changes in carbon dioxide affect the total viral assemblages of two marine alga ecosystems. The first is giant kelp, Macrocyctis pyrifera and the second are rhodolith algae. His experiments were conducted in a controlled environment in aquarium tanks; the sample water was filtered through a 0.22 um pore to isolate phages from larger microbes. The phages are further concentrated using ultracentrifugation and a cesium chloride gradient. The viral DNA is subsequently extracted for high-throughput sequencing and phage identification. Viruses are highly important factors in global marine ecology and understanding how climate-change factors influence the viruses may suggest possible consequences over time.
During the summer of 2014, Ben worked as a foreign-travel research assistant in Dr. Fabiano Thompson’s microbial genetics lab at Universidade Federal do Rio de Janeiro (UFRJ) in Brazil. For two weeks he studied DNA extraction techniques and extracted bacterial samples from coral environments in the Abrolhos Bank. The DNA samples were vacuum-dried, which allowed transport back to the US.
Ben has applied for PhD programs in microbiology and molecular biology and hopes to conduct medical research in a governmental setting such as with the CDC or Department of Defense.

DUYEN TRANG, Psychology, minor in Statistics
IMSD Mentor: May Yeh, Ph.D.

Duyen joined the IMSD Program in June 2013 as a Psychology major with a minor in Statistics. She is currently conducting research at the Child and Adolescent Services Research Center (CASRC) under the mentorship of Dr. May Yeh. The laboratory focuses on children’s mental health services with an emphasis on cultural issues. Duyen’s previous project investigated factors that may be associated with cognitive match, or agreement, between parents and therapists on beliefs about causes of child problems. Understanding factors related to cognitive match may help to increase youths’ therapy attendance, progress, and possibly outcomes. Duyen is currently working on her undergraduate honors thesis that examines the associations between parent-child acculturation gaps and parent-child co-endorsement of child mental health problems. The results will highlight how differences in acculturation levels to mainstream American culture might influence parental agreement with their children on mental health issues. Through various research projects conducted with Dr. Yeh and other advisors (i.e., Dr. Stewart Ehly in summer 2013, Dr. Amy Drahota in summer 2014), Duyen nurtured a research interest in the mental health of underserved populations. She is particularly interested in cultural and contextual factors that promote therapeutic engagement and outcomes. With hopes of increasing competency in the mental health system and reducing unmet needs in ethnic minority communities, Duyen looks forward to pursuing a doctorate in psychology. In addition to research, Duyen is also the Director of Mentorship for the SDSU Psychology Mentoring, OutReach, and Education (PsyMORE) program, which promotes student empowerment through peer mentorship. Due to her involvement in different activities, Duyen aspires to become a university professor to continue conducting research and support diverse students. Duyen recently applied to graduate programs and will earn her B.A. in Psychology in Spring 2015.
