Postdoctoral Fellows

Arun Patil, Ph.D.


Arun obtained his Bachelor’s degree (Microbiology), Post Graduate Diploma (Bioinformatics) and Master’s degree (Bioinformatics) in India. Working with professor Akhilesh Pandey at Institute of Bioinformatics, India and Pandey´s laboratory at Johns Hopkins  he carried out computational analysis and interpretation of proteomics and next-generation sequencing data as part of his Ph.D. thesis. He has contributed to the development of first draft of the human proteome.

His Ph.D. thesis work at the Institute of Bioinformatics and KIIT University, India, was on computational approaches to decipher novel translational events and post-translational modifications. He also worked as lecturer at the Center for Systems Biology and Molecular Medicine at the Yenepoya Research Centre, Yenepoya University, Mangalore, India with Dr. T. S. Keshava Prasad.

In Halushka’s laboratory he is developing a GUI for miRNA analysis pipeline and proteogenomics analysis involving GTEx and high-throughput data.

Graduate Students

Tim Nieuwenhuis


Tim Nieuwenhuis earned his B.S. in Biochemistry & Microbiology from Dickinson college in 2017. There he completed undergrad research on wild yeast discovery and yeast stress response in the lab of Dana Somers. Currently he is a graduate student in the Johns Hopkins Human Genetics Program, where he explores the various drivers of variation in -omic technology, primarily bulk RNA-seq.

Ana (Annie) Jenicke


Annie got her B.S. from Portland State University, where she worked in material science. Currently, she is in the Pathobiology program at Johns Hopkins. She is working on optimizing expression micro dissection for next generation sequencing of miRNAs. She also loves the dark hallways under the hospital.

Elise Walsh

Elise earned her B.S. in Biotechnology and Molecular Bioscience from the Rochester Institute of Technology in 2018. She did her undergraduate research at Roswell Park Comprehensive Cancer Center, focused on breast cancer epidemiology and metabolic changes in prostate cancer. Currently a graduate student in the Johns Hopkins Human Genetics Program, Elise is working on xMD DNA sequencing, particularly clinical applications for pancreatic cancer.
