Department of Biological and Agricultural Engineering

Dr. Celso Castro-Bolinaga

Assistant Professor
Ph.D. (2016), Virginia Tech

Research Interests: River mechanics and sediment transport, environmental fluid mechanics, and computational fluid dynamics

Castro-Bolinaga received his M.S. and Ph.D. in civil engineering from Virginia Tech in December of 2012 and August of 2016, respectively. Castro-Bolinaga completed his undergraduate studies in January of 2009 at Universidad Católica Andrés Bello in Caracas, Venezuela, where he then worked for nearly two years as a hydraulic project engineer in a private consulting firm. His research focuses on the application of computational fluid dynamics to environmental fluid mechanics, and river hydrodynamics and morphodynamics. It encompasses natural processes that are primarily governed by the dynamic interactions among water flow, sediment transport and the geomorphic evolution of the riverbed. Specifically, his work aims to provide a better understanding of how the scales associated with these interactions govern the propagation of large amounts of loose sediment that are suddenly deposited within riverine environments, referred to as sediment pulses.

The Hsiao group seeks to apply the fundamental understanding of colloidal particles and their microscopic interactions to design soft matter with unusual macroscopic properties. Hsiao is interested in linking the flow and mechanical properties of soft materials to their microscale dynamics and structure. Much of her work will involve using experimental and modeling techniques to design systems for which there is complete control over the particle shape, surface chemistry and assembly kinetics. Anisotropic particles, multi-dimensional lithographic printing and a combination of highspeed confocal microscopy and rheological methods will be used to achieve optimal mechanical and functional properties in a broad class of bio-inspired materials.

Jhala received his B.S. in computer engineering from Gujarat University (2001) and M.S. (2004) and Ph.D. (2009) in computer science from NC State University. Jhala’s research group investigates computational structures and methods that are useful in representing and mediating human interpretation and communication of narrative in interactive visual media, such as film and games. The Jhala research group uses symbolic and probabilistic tools to represent and construct coherent visual discourse and apply generative techniques for automated and semi-automated tools to interpret and collaboratively create visual narratives. Past projects include development of games for eliciting aesthetic and emotive preferences in domains such as photographic composition, aesthetics of play for highly skilled game players and gestural aesthetics of dance. Methods used in the lab vary from analysis of existing data sets (such as analysis of movies or game replays), development of games and systems to elicit specific type of behavior and development of novel designs to push the boundaries of creativity through computation.

Dr. Alessandra Scafuro

Assistant Professor
Ph.D. (2013), University of Slerno, Italy

Research Interests: Theoretical foundations, practical applications of cryptography

Scafuro received her B.S., M.S. and Ph.D. in computer science from the University of Salerno, in Italy. She was a postdoctoral researcher at the Computer Science Department at UCLA. Prior to joining NC State, she held a joint post-doctoral position at Boston University and Northeastern University. Presently, she studies the problem of designing protocols for secure computation. The goal of secure computation is to allow several parties to compute a function of their joint inputs in such a way that all participants learn the output of the function but do not learn the inputs of the other parties. This problem is relevant in scenarios where multiple parties are interested in evaluating function on sensitive data that must remain private, for example, running tests on medical records. While from a theoretical point of view, this problem has been extensively studied, the challenge today is to design protocols that are efficient and usable in real world applications, such as analysis of large data sets.

Grace received his B.S. in mechanical engineering from the University of Missouri and received his M.S. and Ph.D. in mechanical engineering from the University of Oklahoma. Prior to joining the NC State faculty, he spent four years as an assistant professor of mechanical and aerospace engineering with a secondary appointment in biomedical engineering at the University of Miami. Prior to joining the faculty at Miami in 2012, Grace spent five years as an aerospace engineer with the U.S. Air Force at Tinker Air Force Base in Oklahoma City. Currently, Grace studies the interaction of polymeric composites with their environment, and attempts to either (a) mitigate or prevent the long-term effects of environmental degradation due largely to fluid contamination or (b) exploit these interactions to achieve novel functionality. This research focus crosses into biomedical and civil/environmental engineering via nanocomposite-based sensors and in vivo degradation of polymeric implants. In the aerospace field, Grace studies diffusion kinetics in polymer composites and the effect of penetrants on both structural and electrical (radar) properties of aircraft/spacecraft composite structures. The majority of this research is experimental but significantly supplemented by theoretical techniques.

Understanding the basic mechanisms of degradation of materials at the nanostructure level is necessary for the development of predictive models of the materials performance and for the design and development of better materials. Materials of interest include advanced alloys for structural and cladding applications in advanced nuclear systems (e.g. austenitic steels, advanced ferritic/martensitic steels, oxide-dispersion-strengthened (ODS) steels), high-temperature ni-based alloys, zirconium alloys and nanocrystalline metallic systems. Characterization techniques of predilection include both in-situ and ex-situ techniques e.g. in-situ irradiation in TEM, in-situ straining in a TEM, electron microscopy techniques, XRD, and synchrotron XRD.
