    Cindy Barba, PhD

    Laboratory of Dr. Elina Zuniga
    Department of Molecular Biology

    My research seeks to understand the role of pDCs in head and neck cancers. pDCs are known to become exhausted and loose their function within tumors. Additionally, high pDC tumor infiltration can be harmful for patients. Understanding the mechanisms that drive pDC exhaustion can lead to therapies that work by reversing or preventing pDC exhaustion in head and neck cancers.

  • Christian Cazares, PhD

    Christian Cazares, PhD

    Laboratory of Dr. Bradley Voytek
    Department of Cognitive Sciences

    Throughout the animal kingdom, social species establish social hierarchies and use social rank to guide the appropriate expression of dominance behaviors that are critical for survival. My research uses mouse models to characterize how orbitofrontal cortex neurons process social ranking information and evaluate how their interactions with serotonergic systems influence the expression of social dominance behaviors. Developing a better understanding of the neuronal mechanisms governing the appropriate expression of social behaviors will provide great value to clinicians and translational researchers wanting to treat impairments in control of social behaviors that are found in psychiatric disease.

  • Sedelia Dominguez, PhD

    Sedelia Dominguez, PhD

    Laboratory of Dr. Fabian Rivera-Chavez
    Department of Pediatrics

    My research focuses on understanding the interactions that contribute to the survival of Vibrio cholerae, which is a bacteria that causes the severe diarrheal disease known as cholera. I am specifically investigating how the bacteria evades intestinal immunity to promote its survival. By investigating these mechanisms, we will gain insight into how to develop cost-effective therapeutics to treat intestinal bacterial infections.

  • Hailey Edwards, PhD

    Hailey Edwards, PhD

    Laboratory of Dr. Deborah Yelon
    Division of Biological Sciences

    My research focuses on understanding the molecular mechanisms that specify the identity of different cardiac populations during embryonic development. My project specifically focuses on the molecular pathways involved in the specification of cardiac pacemaker cells, a small population of specialized cardiomyocytes that are essential for maintaining a normal cardiac rhythm.​​​​

  • Matthew Ellis, PhD

    Matthew Ellis, PhD

    Laboratories of Dr. Farah Sheikh and Dr. Andrew McCulloch
    Department of Medicine

    My research focuses on cardiac conduction and physiology, with an emphasis on understanding the basis for arrhythmogenic disease. By increasing our knowledge of irregular heart patterns, we can better devise treatments and interventions for patients.

  • Arnold Gutierrez, PhD

    Arnold Gutierrez, PhD

    UC San Diego Chancellor's Postdoctoral Fellow
    Laboratory of Dr. Michael Taffe
    Department of Psychiatry

    My research examines the behavioral effects of drug inhalation in pre-clinical models. A major focus of this work is on the long-term effects of repeated opioid vapor inhalation during adolescence. The aim of this work is to better understand how route of administration and age of drug exposure contribute to changes that influence drug-taking behavior later in life.

  • Alexandria Hoffman, PhD

    Alexandria Hoffman, PhD

    Laboratory of Dr. Victor Nizet
    Department of Pediatrics

    Sepsis is responsible for one third of hospital deaths in the United States. My research applies novel bio-mimicking nanotechnology to the treatment of immune dysfunction during sepsis with the goal of improving survival and quality of life after sepsis diagnosis.

  • Francisco Méndez Díaz, PhD

    Francisco Méndez Díaz, PhD

    Laboratory of Dr. Kevin Corbett
    Department of Cellular and Molecular Medicine

    My research determines how sister homologs are stabilized and maintained, particularly by chromosomal axis core proteins, to promote genome stability throughout the meiotic process. Specifically, I am utilizing yeast genetics, biochemistry, and structural biology to determine how the axis core protein Red1 and the meiotic cohesin complex interact together to take part of chromosome axis assembly. My research will contribute to the field of meiosis by providing new insights into chromosome axis assembly, a requirement for driving meiosis.

  • Alexia Perryman, PhD

    Alexia Perryman, PhD

    Laboratory of Dr. Laura Crotty Alexander

    Julio Pimente​l, PhD

    Laboratory of Dr. JoAnn Trejo
    Department of Pharmacology​
    Breast cancer is the most common and second-leading cause of cancer deaths among women in the United States. My research focuses on the role of deubiquitinases in regulating G protein-coupled receptor-mediated invasion and metastasis in triple-negative breast cancer, which is an aggressive form of breast cancer. ​
  • Alexis Reyes, PhD

    Alexis Reyes, PhD

    Alyssa Rodriguez, PhD

    Laboratory of Dr. Kevin Corbett
    Department of Cellular and Molecular Medicine

    Issues in meiosis can lead to miscarriages, cancer, and chromosomal abnormalities in humans. To ensure the successful transfer of genetic information from one generation to the next, DNA recombination must coordinate programmed double stranded DNA breaks via chromatin interacting proteins. I investigate the chromatin binding region of metazoan HORMA domain (HORMAD) containing protein Hop1 and how it interacts with chromatin structurally and functionally, utilizing structural biology and biochemical techniques.​
