Milestones

Sonia Bansal and Haris Durrani December 18, 2014
Two Columbia Engineering seniors—Sonia Bansal and Haris Durrani—will present their research at the prestigious National Collegiate Research Conference (NCRC) in January. The three-day gathering, hosted by Harvard University, showcases some of the most promising and significant work from rising undergraduate leaders in the global research sphere. Bansal, a biomedical engineering major, will share a poster examining her work in orthopedic tissue engineering, “Bell-shaped Dose Response Of Sodium Pyruvate On Properties Of Tissue Engineered Cartilage,” which was supervised by Biomedical Engineering Professor Clark Hung. Durrani, an applied physics student, will present a poster on his research concerning “Space Debris: Observation, Mitigation, Remediation and Their Legal Factors,” which was supervised by Professor of Professional Practice (and former NASA astronaut) Mike Massimino BS’84.
Kathy McKeown December 15, 2014
eBrevia, based on technology out of Computer Science Professor Kathy McKeown’s lab, recently raised $1.5 million in seed funding from Connecticut Innovations and a number of seed and angel investors. Using machine learning techniques, the company’s software can extract and summarize legal provisions from a wide array of legal documents, with applications for legal due diligence, contract management, and document drafting.
Xin Li December 12, 2014
Xin Li, a PhD candidate in IEOR, has won the Informs-Financial Services Section (FSS) Best Student Paper Competition for her paper on the optimal trading of mean reverting prices generated by pairs of exchange-traded funds (ETFs). She presented her work at the INFORMS Annual Meeting in San Francisco in November. The paper was also recently accepted by the International Journal of Theoretical & Applied Finance. Li, who works with IEOR Assistant Professor Tim Leung, is focused on financial engineering and, specifically, optimal timing strategies for trading and risk management.
John Kymissis December 12, 2014
Chromation, a Columbia start-up out of Electrical Engineering Professor John Kymissis' lab, recently received $1 million in funding. This compact, programmable spectral sensor platform allows for software selection of measurement wavelengths, improving the capability and performance of consumer electronics by providing a low-cost way to integrate color and light measurement into products.
Vasileios Kemerlis December 5, 2014
Vasileios Kemerlis, a PhD student in the Department of Computer Science and member of the Network Security Lab (NSL) at the Engineering School, recently brought home the top prize for the Best Applied Research Paper from Cybersecurity Awareness Week's expansive cybersecurity competition, hosted by NYU's Polytechnic School of Engineering. His paper, "ret2dir: Rethinking Kernel Isolation," authored with Computer Science Professor Angelos D. Keromytis and applied research scientist Michalis Polychronakis, demonstrates that the fundamental structure of modern operating systems is more vulnerable to potential hacks than previously known. Their paper introduced return-to-direct-mapped memory (ret2dir), a new exploitation technique that bypasses various state of the art software protection mechanisms and proposes a new approach for securing devices against such novel attacks.
