Our Team

Anthony Carvalloza
Director

Anthony Carvalloza is the Chief Information Officer and Associate Vice President at The Rockefeller University where he provides oversight for Information Technology, High Performance Computing, Bioinformatics and the Markus Library, to support and accelerate the research of the University's faculty and staff.

Anthony received his bachelor's degree in information sciences, magna cum laude, from Syracuse University. He was intrigued early on by algorithms and their use in cryptography. While interning at Organon Inc., a pharmaceutical company in New Jersey, Anthony became interested in how computational approaches could be applied to advance biomedicine. After graduating, Anthony accepted a position at Merck Research Labs in Rahway, NJ. He was at Merck for nearly five years, during which time he was promoted to Senior System Analyst.

In 2004, Anthony accepted a position as Lead Informatics Systems Analyst at the newly formed Florida campus of The Scripps Research Institute (TSRI). As one of the first employees of the institution, he helped develop the initial computing and software infrastructure that supported a new model of integrated translational research within an academic research university. Eventually, Anthony was promoted to Director of Informatics and Information Technology, in which he formed the institution's first bioinformatics core, and assumed responsibility for the high performance computing and software engineering efforts across both TSRI campuses, in addition to the IT operations for the Florida campus.

Anthony joined The Rockefeller University in May of 2015. At Rockefeller he is leveraging Rockefeller's IT infrastructure through the recently formed High-Performance Computing Center (2016) and the new Bioinformatics Resource Group (2017). This is enabling him to create an environment that increases the University's knowledge, resources and capabilities in the data sciences and gives our scientists access to the infrastructure, tools, and expertise that support and enhance their visionary research.

Anthony has published multiple peer-reviewed scientific and technical manuscripts and book chapters, and has served on the board of directors of several organizations, including the South Florida Technology Alliance.

Emre Kurtoğlu
MLE II

I received my Ph.D. from The University of Alabama in May 2024. Main focus of my research was on radar signal processing and indoor monitoring applications of automotive radars including human activity recognition, hand gesture and sign language recognition. I also worked on automated temporal segmentation of RF data [1], synthetic and simulated RF data generation, separation of raw radar signals from multiple targets [2] and most recently, developed a multi-modal (RF + camera) sign language-controlled Chess game [3].

Heng Zhao
MLE II

I completed my PhD in Mathematics at the University of Houston. During my PhD, I mainly focused on integrating model-based and learning-based strategies for Computational Imaging and Biomedical Image Analysis. By integrating conventional model-based techniques, such as compressive sensing and wavelets, with deep learning models, I aimed to improve theoretical understanding and enhance the interpretability of deep learning in practical applications.
