Postdoctoral Fellow
	Kevin Jacob jkevin@iastate.edu I am a Postdoctoral researcher at Iowa State University working along with Dr. Sid Pathak. I completed my PhD from the Indian Institute of Technology Bombay under the guidance of Prof. Nagamani Jaya Balila in the Micro Mechanics of Materials lab. During my PhD I worked on the deformation as well as precipitation behaviour of severe plastically deformed Maraging steels. I have used the transmission electron microscope and the atom probe tomography tools to characterize the effect of deformation on the nanometre sized precipitates. Understanding strain localization and planar slip behaviour in Maraging steels through digital image correlation was another aspect into which I obtained proficiency over the course of my PhD. Stress localizations on the differently shaped precipitates observed were also modelled using finite element simulations. For my Postdoctoral research period at ISU, I intend to work more extensively on the nano scale deformation behaviour that Dr. Sid and his group are extensively skilled in, along with bringing to the table the nano level characterization tools that I am more adept with to get a better picture of the deformation behaviour. Apart from research, I love to trek and travel along with playing any sort of sports in which I could get myself involved.
	Zongyang Lyu zlyu@iastate.edu I got my PhD from the Department of Materials Science and Engineering, University of Tennessee, Knoxville in 2023 under the guidance of Prof. Peter Liaw and Prof. Yanfei Gao. During my PhD, I worked on two NSF projects, i.e, “Fundamental Study of Low-Cycle-Fatigue Behavior of High-Entropy Alloys” and “In situ Diffraction and Cohesive-Zone Studies of the Fatigue-Crack-Growth Behavior in Mg Alloys”. In situ diffraction techniques are used to investigate the phase transformations and deformation mechanisms in these two projects. For the in situ diffraction experiments, we used the cutting-edge facilities at VULCAN, Spallation Neutron Source (SNS), Oak Ridge National Laboratory (ORNL) and 11-ID-C, Advanced Photon Source (APS), Argonne National Laboratory (ANL). For my postdoc research in Prof. Sid Pathak’s group at ISU, I am working on a Department of Energy (DOE) funded project, “Direct Production of ODS Ferritic Alloys for Long-life Reactor Fuel Bundles”. I will work closely with the Ames National Laboratory and the Center for Integrated Nanotechnology (CINT) at Los Alamos National Laboratory (LANL). Apart from research, I like doing sports and traveling to national parks.

I developed interest in research during an internship at the Indian Institute of Technology(IIT), Madras. After that, I was awarded a summer research fellowship by the Indian Academic of Science, India. My research during 3rd year of undergrad study was focused on “Development of Ceramic Matrix Composite Coating on Metal Substrate by lases cladding”. In Final Year, I worked on the piezoelectric performance of Electrospun Poly(Vinylidene Fluoride) non-wovens. Currently, I am pursuing my PhD under the guidance of Dr. Sid Pathak. My research is focused on the local structure-property relationships of solders in Terrestrial vs. Microgravity environments. Apart from my research, I like to go hiking, long-distance biking, and playing cricket & badminton. I spend my free time reading books and watching sci-fi videos.
