Pharmacology and Toxicology Post-Doctoral Researchers

The Pharmacology and Toxicology Department has a small and vibrant community of trainees consisting of graduate students, post-baccalaureate students, and postdoctoral fellows from across the country (and the world). The newly reformed Association for Pharmacology and Toxicology Students welcomes all trainees, in addition to staff who are thinking about pursuing a graduate degree, to their events. 

13 Post-doctoral Researchers work in 9 different labs in the Department of Pharmacology and Toxicology Lab. Read more about them and their research below.

Post-Doc News

"I recently presented my research at the Cold Spring Harbor Laboratory Zebrafish Neurobiology 2025 Meeting. My presentation, titled “Zebrafish Reveal TrkA as a Molecular Target for Reducing Opioid Self-Administration,” highlighted our findings that TrkA signaling may reduce opioid-seeking behavior. This work positions zebrafish as a powerful model for identifying receptor-level mechanisms that may underlie opioid reinforcement." November 2025

Pushkar Bansal, PhD

I am a passionate Deep Learning Researcher specializing in computer vision models who aims to induce automation in high-throughput experimentations and analysis. As a computer vision and deep learning researcher, I design, train, and deploy deep learning models related to pre-clinical research. My projects range from automated high-throughput image classification and segmentation to object detection, object measurement, tracking, and predictive modeling. I often work with large-scale images and video datasets. My research aims to optimize model efficiency and accuracy, addressing challenges such as model generalization, interpretability, and scalability. I am constantly exploring the evolving field of AI, keeping up with the latest advancements in deep learning architectures and optimization techniques. I aim to contribute impactful research, collaborate with innovative teams, and develop AI-driven solutions that make a difference in the tech industry and beyond.

Microorganisms are exceptional chemists, capable of producing structurally complex and unique molecules far beyond what we can achieve synthetically. Exploring untapped sources of natural products offers a pathway to discovering these compounds, many of which hold great potential for bioactivity. I'm particularly interested in uncovering how these molecules mediate interactions within their environments, understanding their biosynthetic mechanisms, and exploring chemical modifications to enhance their bioactive properties and broaden their potential applications.

Zachary Brandt, PhD

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 am an inorganic chemist with extensive experience in synthetic and physical bioinorganic chemistry and a strong interest in deepening my knowledge of advanced spectroscopic methods while continuing to advance the field of inorganic chemistry. I enjoy working collaboratively with other scientists and contributing my expertise in synthetic (including air-free) chemistry, spectroscopic (multinuclear/multidimensional NMR, IR, Raman, UV-vis) characterization, computational chemistry (DFT, wavefunction theory, thermochemistry, QTAIM analyses), and X-ray crystallography (crystal growth, data collection/processing, structure solution, structure refinement).

Thankhoe Rants'O, PhD

Tumor metastasis is the principal cause of cancer-related death. Similarly, drug resistance is the major obstacle to effective cancer therapy, driving high relapse and mortality rates. I am studying how epithelial-mesenchymal plasticity drives metastasis in hepatocellular carcinoma (HCC) with the aim of identifying novel pharmacological targets to block metastasis. Similarly, I am studying how kinome rewiring drives chemoresistance; my goal is to devise kinase inhibitor/chemotherapy combinations that prevent HCC chemo-adaption.

Dr. Ashwini Sri Hari

Ashwini Sri Hari, PhD

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.
