Smita Krishnaswamy is an Assistant Professor in the department of Genetics at the Yale School of Medicine and Department of Computer Science in the Yale School of Applied Science and Engineering. Smita’s research focuses on applying machine learning methods to high-throughput high dimensional biological data. Smita has been focusing on using manifold learning and deep learning to develop unsupervised algorithmic approaches to naturally process data, visualize it, understand progressions , find phenotypic diversity, and infer patterns. Some of the key projects developed in her Lab include MAGIC (a tool for imputation and denoising of data), PHATE (a powerful new visualization method for high dimensional data that can unveil progression and cluster structures, and SAUCIE (an autoencoder-based deep learning approach for automatically batch correcting, visualizing, denoising and clustering data). These methods have been applied to a variety of biological applications including embryoid body differentiation, the epithelial-to-mesenchymal transition in breast cancer, lung cancer immunotherapy, infectious disease data, gut microbiome data and population genetics data.
At Yale, Smita teaches two CS/Genetics/Computational Biology cross-listed courses. Advanced Topics in Machine Learning & Data Mining (Spring), and Machine Learning for Biology (Fall). She completed her postdoctoral training at Columbia University in the systems biology department where she focused on learning computational models of cellular signaling from single-cell mass cytometry data. She was trained as a computer scientist with a Ph.D. from the University of Michigan’s EECS department where her research focused on algorithms for automated synthesis and verification of nanoscale logic circuits that exhibit probabilistic effects.
DAVID VAN DIJK, ASSOCIATE RESEARCH SCHOLAR
David completed his PhD at the University of Amsterdam (with Professor Peter Sloot) and the Weizmann Institute of Science (with Professor Eran Segal) in Computational Biology. He used thermodynamic and kinetic models to understand how gene regulation, at the population and single-cell level, is encoded in DNA sequence. Currently he’s an Associate Research Scholar in the departments of Genetics and Computer Science at Yale University. His work focusses on developing new machine learning methods for big biological data, with a focus on applying spectral graph methods and deep learning on single-cell data. He co-developed MAGIC, a single-cell data imputation method, and PHATE, a dimensionality reduction and visualization method.
Kevin Moon, Postdoctoral Associate
Co-advised by Ronald Coifman in the Mathematics and Computer Science departments. He completed my PhD in Electrical Engineering and Computer Science (EECS) under Dr. Alfred Hero at the University of Michigan in Ann Arbor in 2016. He completed an MS (2016) in Mathematics at Michigan and an MS (2012) and BS (2011) in Electrical Engineering from Brigham Young University in Provo, Utah.
Kevin's general research interests are in the development of theory and applications in machine learning, big data, information theory, manifold learning, statistical signal processing, statistical learning theory, estimation, graphical models, and random matrix theory. His main projects currently focus on data visualization, data denoising, and nonparametric estimation of information theoretic measures such as entropy, mutual information, and information divergence. I focus primarily on single-cell data (e.g. CyTOF and single-cell RNA-sequencing).
