Dissertation: Determining the role of E3 ligase-substrate interation networks during early development
We have developed a microfluidics-based, high-throughput in vivo CRISPR/Cas9 genetic screening platform (MIC-Drop) that can be coupled to multiple downstream phenotypic readouts to examine gene function at a large scale in a vertebrate system. There are 634 human E3s, many of which have not been thoroughly characterized because of the complexity of the ubiquitin system and a lack of high-throughput technologies to study it have hindered the elucidation of the functions of the majority of E3s in early development. We propose to advance the understanding of the functional roles of E3s during early development by using MIC-Drop to mutagenize all E3 ligase orthologs in the zebrafish, perform morphometric evaluations of the mutagenized larvae to pinpoint E3-induced developmental changes and investigate the mechanisms of E3/E3-substrate pair function in development using both proteomics and classical biochemical approaches.

Dissertation: Changes in structure and function of NG2-Glia during viral encephalitis
Theiler’s Murine Encephalomyelitis Virus (TMEV) is used to model virally induced seizures and epilepsy in mice. NG2-glia, also known as oligodendrocyte precursor cells, may contribute to the clearance of virus from the brain and may also contribute to seizure burden during acute infection. I am studying the synapses formed between NG2-glia and neurons, as well as the phagocytic activity of NG2-glia, in response to TMEV infection.

Research: Gut microbiota and meningeal immune dynamics in viral-induced neuroinflammation and seizure development
Viral-induced neuroinflammation plays an important role in seizure development, yet the mechanisms by which viral infections modulate immune responses and their involvement in seizure initiation are not well understood. My research employs a mouse model of viral-induced epilepsy to explore the roles of gut microbiota and meningeal immunity in neuroinflammation and seizure development. My work focuses on how brain-infiltrating immune cells, such as macrophages, contribute to changes in the CNS that induce seizures and how the gut microbiota and meninges modulate such changes.

Dissertation: Extracellular Vesicle Physiology in the Conventional Outflow Pathway in Glaucoma
Glaucoma is a significant contributor to vision impairment and vision loss across the world, and lowering intraocular pressure is the current mainstay of treatment. The conventional outflow pathway is the major generator of resistance to aqueous humor outflow in the eye, and dysregulation of extracellular matrix homeostasis in glaucoma has been found to contribute to pressure buildup. Our lab is interested in understanding the role of extracellular vesicles in the pathological remodeling that occurs throughout the conventional outflow pathway in glaucoma.

Dissertation: Mechanisms Underlying the Histone Modifier Kdm6b's Contribution to the Development of autism
My research focuses on understanding the mechanisms underlying the development of autism spectrum disorder (ASD) by investigating the role of the histone modifier Kdm6b. Specifically, I aim to determine how Kdm6b influences social behavior by promoting GABAergic neuron development and enhancing the transcription of ASD risk genes through interactions with other chromatin remodelers. By elucidating these pathways, my work seeks to contribute to the development of more effective treatment for ASD, addressing the current gap in linking genetic variants to neuronal mechanisms.

Dissertation: Regulation of mitophagy by t-tubule microdomains in cardiomyocytes
Heart failure with preserved ejection fraction (HFpEF) is marked by mitochondrial dysfunction and increased oxidative stress. To better understand the molecular basis for this dysfunction, I study the regulation of mitochondrial quality control by cardiomyocyte transverse-tubule microdomains. Restoration of t-tubule microdomains offers a potential therapeutic approach to restoring mitochondrial function.

Dissertation: Discovery of Novel Antibiotic Peptides and Their Biosynthesis from Great Salt Lake Actinomycetota
From a combination of genomic, metabolomic, and activity-guided screening techniques, our preliminary data show that actinomycetota isolated from Great Salt Lake sediment represent unique evolutionary lineages with a wealth of undescribed biosynthetic potential and many have demonstrated activity against multidrug resistant ESKAPE pathogens. Their genomes contain several novel RiPP biosynthetic gene clusters (BGCs), including many lasso peptide and linaridin BGCs with previously unreported post-translational modification enzymes (PTMEs). My goals are to isolate these RiPPs in order characterize their structures and activities to describe their biosynthesis and characterize these potentially novel PTMEs.

Dissertation: Coordinated Regulation of TRPA1, TRPV3, and Kinase Signalling Pathways in Lung Epithelial Cell Damage and Repair Following Environmental Pollutant Exposure
TRPA1 and TRPV3 have been found to be differentially expressed following various forms of lung epithelial cell injury. Kinase signaling pathways linked to growth factor signaling, and potentially TRP channels, may provide protection against environmental air pollutant injury in lung epithelial cells. Through inhibition or activation of various kinases followed by activation of TRPA1 and/or TRPV3, this may offer protection against damage and aid in lung epithelial cell recovery.

Dissertation: The role of redox balance in cyanide toxicity and mitochondrial disease
Cyanide poisoning and Leigh syndrome are both related conditions involving major neurological consequences, mitochondrial dysfunction and redox imbalance. Because of the limitations and/or lack of treatment for both, we aim to establish the therapeutic value of restoring redox balance. We will conduct these studies in zebrafish models of Leigh syndrome and cyanide toxicity.

Dissertation: Cell-type-specific adaptations in the dorsal striatum of habitual cocaine-seeking behavior
My research involves the study of cell-type-specific adaptations in the dorsal striatum of habitual cocaine-seeking behavior. Excitatory synaptic function and plasticity following prolonged cocaine administration is likely contributing to the induction of behavioral states underlying habitual control of behavior. It is hypothesized that better understanding of excitatory synaptic transmission in the context of addiction will pave the way for therapeutic targets for novel treatments.

I joined the Peterson lab in late 2020, after earning my PhD in Cell and Developmental Biology working in the lab of Dr. Brian Link at the Medical College of Wisconsin. As a postdoc in the Peterson lab I'm studying how skin functions as a sensory organ contributing to touch, itch, and pain sensation. To that end, I'm performing high-throughput genetic screens in zebrafish, and examining how the genes identified in these screens regulate the join development of the skin and it's innervating sensory neurons. I'm also using zebrafish to model rare and/or undiagnosed diseases, with a goal of developing screening platforms capable of identifying potential therapeutics for patients with these conditions.

I've always been fascinated about understanding underlying pathogenic mechanisms that contribute to disease phenotypes in order to identify novel drug targets. Epilepsy is a neurological disorder that affects more than 65 million people globally and has a complex pathophysiology. Pediatric epilepsies, in particular, are devastating and negatively impact the quality of life of patients and their caregivers. My research interests are multifaceted and include the following: (i) investigating how environmental pollutants might affect seizure outcomes in the Dravet Syndrome, a rare but catastrophic pediatric epilepsy (ii) understanding the role of metabolic alterations in causing sudden unexpected death in epilepsy (SUDEP) in Dravet Syndrome, and (iii) screening of drug compounds in the Dravet Syndrome mouse model which would aid in the identification of the next novel compound that could potentially treat certain genetic pharmacoresistant epilepsies. I work with mouse models of epilepsy, in particular the Dravet Syndrome mouse model. I have also worked with in-vitro and zebrafish models of hyperexcitability/seizures.
