Graduate Student, Alyssa Hasty laboratory, Molecular Physiology and Biophysics
I study the role of eosinophils in adipose tissue homeostasis, specifically during periods of weight gain or weight loss. In particular, I seek to understand how eosinophils impact key aspects of adipose tissue physiology such as macrophage inflammatory state, vascularization, extracellular matrix remodeling, and adipocyte insulin sensitivity.

Titin, the largest known protein, is indispensable for the structural integrity and function of the cardiac sarcomere. Yet, how such a massive ~3 mDa structural protein is maintained within the highly ordered sarcomere complex, while under continuously alternating tension, is unknown. My thesis focuses on elucidating the mechanisms mediating sarcomere homeostasis in human induced pluripotent stem cell-derived cardiomyocytes. Using CRISPR/Cas9 gene editing, I generated a novel model in which I can directly visualize sarcomeric titin in order to address fundamental questions regarding titin turnover, which is critical for sarcomere homeostasis.
Graduate Student, John Penn Laboratory, Molecular Physiology & Biophysics
I am currently studying inflammation in diabetic retinopathy in Dr. John S. Penn‘s Laboratory.
Graduate Student, Maureen Gannon laboratory, Molecular Physiology & Biophysics
Prostaglandins are important modulators of an array of physiologic functions including insulin secretion and systemic inflammation. In the Gannon lab, I focus on the specific roles of the prostaglandin E2 receptors EP3 and EP4 and how they regulate processes involved in β-cell mass expansion. I am using pharmacological tools to examine the effects of EP3 and EP4 signaling in β-cell proliferation and β-cell survival in isolated mouse and human islets. I am also studying the effects of an EP3 antagonist and an EP4 agonist on β-cell proliferation and β-cell survival in the db/db mouse model of type 2 diabetes.

MD PhD Student, Hasty laboratory, Molecular Physiology & Biophysics
I am studying the role of macrophages in maintaining iron homeostasis in adipose tissue. Specifically, we have identified a subset of resident macrophages that compensate for excess iron in the tissue. We are currently interested in depleting this population of macrophages in order to assess their importance in maintaining the health of adipocytes. In future studies we will address the importance of iron handling by macrophages in obesity, and the temporal distribution of iron in adipose tissue and liver tissues.

Graduate Student, Powers laboratory, Molecular Physiology & Biophysics
My thesis in the Powers laboratory addresses basic questions of diabetes pathology, specifically (1) the functional consequences of chronic hyperglycemia on human pancreatic islets in vivo, and (2) the effects of ErbB growth factors on islet growth and function
Graduate Student, Gannon laboratory, Molecular Physiology & Biophysics
I am interested in understanding the role of the transcription factor Oc1 (Onecut1) in pancreas development and disease. Oc1 is essential for development of the endocrine pancreas, so I am investigating its interaction its cofactor Pdx1 in that role. I have thus far determined that proper dosage of both Oc1 and Pdx1 is necessary for endocrine cell differentiation and that defects established during development persist into adulthood. I am further interested in identifying the direct targets of Oc1 during pancreas development since so little is known about its direct regulatory role.

MD PhD Student, Cone laboratory, Molecular Physiology & Biophysics
In the Cone lab, I study the pathophysiology associated with deletion of the MC4R, the most common monogenetic obesity syndrome in man (1/5000 allele frequency). Using the mouse as a model organism, I am characterizing the cardiovascular, metabolic and energetic consequences that result from MC4R deletion. Observations from my research have furthered the need to identify and monitor patients with this distinct obesity syndrome.
More broadly, my research interests include: energy metabolism, mitochondrial physiology, cardiovascular pathophysiology, pharmicogenomics, and gene environment interactions.

Graduate Student, Weil Laboratory, Molecular Physiology & Biophysics
RNA Polymerase II transcriptional activation contributes importantly to the regulation of gene expression by controlling mRNA biosynthesis. A central driving force of the activation process is provided by the concerted action of a DNA-binding transfactor and at least one coactivator. I am interested in defining the transfactor-coactivator interactions required for activation. The specific goal of my current work in the Weil lab is to determine the specific domains the Rap1 transcriptional activator uses to interact with the general transcription factor TFIID to drive activation of the budding yeast S. cerevisiae ribosomal protein genes. I combine genetic, biochemical, and biophysical approaches to accomplish this goal.

Graduate Student, O'Brien laboratory, Molecular Physiology & Biophysics
The prevalence type 2 diabetes (T2D) continues to increase worldwide. Multiple SNPs associated with altered risk of T2D have been identified through genome wide association studies including rs13266634 in the SLC30A8 locus, which encodes zinc transporter 8 (ZnT8). In addition, rare mutations resulting in SLC30A8 haploinsufficiency are protective against T2D. Using several mouse models, we are investigating the role that ZnT8 plays in beta cell function and the potential of ZnT8 as a therapeutic target for T2D.

Graduate Student, Jacobson laboratory, Molecular Physiology & Biophysics
The deterioration of pancreatic islet function is a hallmark of type 2 diabetes mellitus (T2DM). In the Jacobson lab, I study the physiological functions of an islet potassium channel, TALK-1. TALK-1 is the most transcriptionally abundant potassium channel in insulin-secreting β-cells, and polymorphisms in TALK-1 are associated with an increased susceptibility for T2DM. However, the molecular mechanisms underlying TALK-1’s contributions to T2DM pathogenesis remain unclear. Using a variety of experimental approaches, including electrophysiology, calcium imaging, hormone secretion, and mouse models, we have recently found that TALK-1 channels regulate islet calcium homeostasis and insulin secretion. These findings suggest that TALK-1 could serve as a therapeutic target in T2DM.
