About Me

I am a PhD candidate in Computational Biology at Brown University, currently studying at Princeton University with advisor Ben Raphael. My research is focused on developing algorithms for understanding tumor heterogeneity. Recent projects include developing a probabilistic method to identify structural variants from whole-genome linked-read sequencing data and using machine learning to cluster cells from high-throughput single-cell RNA-seq data.

Brown University

PhD Candidate

I work with advisor Ben Raphael to develop algorithms for understanding tumor heterogeneity. Recent projects include developing a probabilistic method to identify structural variants from whole-genome linked-read sequencing data and using machine learning to cluster cells from high-throughput single-cell RNA-seq data.

Brown University

NSF IGERT Fellow

I am collaborating with ecologists to assemble a high-quality genome and transcriptome for the barnacle species S. balanoides and to characterize allele frequencies and microbiome composition differences across the upper and lower extremes of the intertidal zone. 

École Polytechnique Fédérale de Lausanne (EPFL)

Blue Brain Project Intern

I developed software to synthesize neuron morphologies of different cell types for the Blue Brain Project. The software uses diffusive particle dynamics to “grow” a population of neurons in parallel, allowing growing neurons to interact with each other and create realistic neuronal arbors.

Carnegie Mellon University

Undergraduate Researcher

I worked under Dr. Robert Murphy to develop algorithms to create generative models of neuron shape as part of the CellOrganizer tool.

Teaching Experience

Prison Teaching Initiative

Math Instructor

I taught Elementary Algebra and Basic Math to inmates at Garden State Youth Correctional Facility and Albert C. Wagner Youth Correctional Facility. The courses are accredited through Raritan Valley Community College.

Princeton University

Student Supervisor, Laboratory Learning Program

I designed a research project and supervised a high school intern as part of the Laboratory Learning Program.

Princeton University

Undergraduate Research Mentor

I mentored junior independent work for COS397

Princeton University

Programming mentor

I mentored Princeton undergraduates in website and app development as part of Princeton Summer Programming Experiences

netNMF-sc

netNMF-sc is a network regularization algorithm for dimensionality reduction and imputation of single-cell expression data.

View Project

Billion Oyster Project Digital Platform data visualizations

I was partnered with the Billion Oyster Project through the Bloomberg Data for Good Exchange Immersion Fellowship. I created a web application for generating plots and figures for visualization of oyster measurement data on the digital platform.

NAIBR

NAIBR (Novel Adjacency Identifying with Barcoded Reads) is a probabilistic method for identifying novel adjacencies created by structural variants. NAIBR utilizes barcoded reads produced by 10X Genomics' whole genome sequencing pipeline to probabalistically model and rank candidate novel adjacencies.

Single Cell Geometries

Software to simulate single cell count matrices from several canonical geometries. Created with members of the Cell Types working group at the Chan Zuckerberg Initiative (CZI) investigator meeting Collaborative Computational Tools for the Human Cell Atlas.

Octduino

The Octduino is an octopus plush that has 12 programmable buttons sewn to its tentacles with conductive thread. We have programmed the buttons to play the 12 notes of an octave so that the Octduino can be played like a piano. The user can also program the Octduino to be a general purpose USB controller, allowing the user use the Octduino to control all types of video games. Octduino placed 3rd at HackPrinceton as well as winning 'Best Hardware' and 'Made My Day'.
