Graduate Student

Erik Ladewig is pursuing a PhD in computational biology in Columbia's Integrated Program in Cellular, Molecular, Structural and Genetic Studies. His current interests include algorithms in statistical analysis of high-throughput data to infer disease mechanisms and evolution. Before attending Columbia he was a member of Eric Lai's laboratory at Memorial Sloan Kettering Cancer Center. While there, his research focused on biogenesis and post-transcriptional modifications of small non-coding regulatory RNAs.
