My research interests have been always been centered around developing computational tools to aid the study of molecular biology or healthcare. During my PhD, I primarily worked on development of Machine Learning algorithms to enable the study of biological phenomenon, such as development and disease progression. After my PhD, my research has centered around 2 broad themes: i) Development of algorithms to study/predict health outcomes, ii) Development of algorithms that enable collaborative science. A somewhat more granular view of my research work can be found below.

Computational tools & analysis to identify genetic drivers of Alzheimer's Disease
My work at Sage Bionetworks focused on developing novel Machine Learning tools to identify drivers of AD. I have been studying the use of manifold learning on RNA-Seq data from post-mortem brain samples of AD patients and controls to predict disease staging and subtypes. Downstream applications of this technique includes studying the effect on biological pathways as a function of disease progression and subtype.

Algorithmic tools for Single Cell RNA-Seq analysis
During my PhD, I developed a novel algorithmic tool for sampling distribution aware pre-processing of sparse Single Cell RNA-Seq (scRNA-Seq) data . Our tool (UNCURL) is also able to incorporate qualitative prior biological information into the pre-processing pipeline and is shown to improve the performance of downstream analytic tasks such as clustering and lineage inference. Additionally, the algorithm was shown to be easily scalable and has led to the development of a web-app to enable online scRNA-Seq data analysis. I also developed a novel algorithm (PIPER) for driver gene prediction for stage-wise scRNA-Seq data . Our tool utilized state-of-the-art network inference techniques for sparse data types and performed differential network analysis to predict the most likely drivers of biological processes.

Novel low-cost protocol for Single Cell RNA-Seq
During early stages of my PhD, I worked on the development of a low-cost scRNA-Seq protocol (Split-Seq) . I was involved both in experimental protocol development as well as the initial data analysis for the project. Our method was shown to scale to hundreds of thousands of cells and had a lower cost-per-cell than most competing methods.

Studying noise-rejection properties of microRNA mediated network motifs
I worked on a systematic mathematical analysis of the noise rejection properties of microRNA mediated incoherent feed-forward loops. Our analysis focused on elucidating the noise rejection properties of this class of network motifs at the population level (extrinsic noise) which led to the identification of parameter spaces where the noise is most efficiently rejected .

A routing app for pedestrians with disabilities
I worked on the development of an algorithmic method for identifying a connected network of sidewalks from publicly curated municipal data from the King county . This connected network of sidewalk was then used in conjunction with sidewalk attributes such as elevation gain/loss and presence of curb ramps to develop a customizable routing app for pedestrians with disabilities.
