About Ethan
Ethan works on cancer immunotherapy, focusing on CD8+ T-cell exhaustion and progenitor-exhausted T cells. He uses single-cell and multi-omics analyses, AI-assisted workflows and research software to compare cell-state definitions and examine their implications for clinical analyses.
He develops reproducible analyses using Python, R, Bash and high-performance computing, with experience using Snakemake and Nextflow.
Previous Experience
Before joining USF, Ethan held research appointments in the NIH Critical Care Medicine Department, where he studied fungal protein function and evolution using sequence analysis, Foldseek and AlphaFold. His earlier laboratory work at Rapid Genomics and the University of Florida included sequencing-library preparation, agricultural genotyping and mammalian cell culture for vaccine research.

About Kashvi
Kashvi studies Alzheimer’s disease using transcriptomics, statistical genomics and machine learning.
Her first-author study combined five bulk RNA-sequencing datasets to identify a 37-gene signature associated with the disease across brain regions, examine its relationship with neuropathology and evaluate it in independent cohorts.
Previous Experience
Kashvi’s broader experience includes cancer genomics, single-cell RNA sequencing, whole-exome and whole-genome sequencing and ChIP-seq. She develops reproducible analysis workflows with Python, R and Linux-based computing tools.

About Tanner
Tanner works on statistical and genomic analyses of non-small cell lung cancer. His work includes somatic mutation analysis to study clonal hematopoiesis and clinical data collection for immunotherapy biomarker and outcome studies.
He uses R, SAS and Python for data management, statistical analysis and visualization, drawing on his training in applied biostatistics and epidemiology. His broader research experience spans Alzheimer’s disease clinical trials, trauma research and infectious disease surveillance.
Previous Experience
Tanner’s previous research includes analyses of Alzheimer’s disease clinical trial availability, effect sizes reported in biomedical studies and statistical support for trauma research. He also gained experience in infectious disease surveillance through an epidemiology internship with the Florida Department of Health.
