My multi-disciplinary
background includes research and teaching with a focus on mathematical
modeling of thermodynamic systems, especially involving nonequilibrium phase
transformations due to fast interface kinetics. Post doctoral studies
at the Center for Engineering in Medicine, a leading research center on
biopreservation run jointly by Harvard Medical School and Massachusetts
General Hospital in Boston, provided me with the sources to move my research
interests into the biomedical field, namely to develop mathematical models
for freezing and vitrification of cells. My ongoing research at Hacettepe
University is on the optimization of a novel automatic controlled
electro-chemical machining (ECM) device that we developed as an R&D
company in the University Technopark with the Techno-Innovation grant from
the Turkish Ministry of Industry and Trade. The long term goal is to further
improve the ECM technique for application to MEMS devices. For my Ph.D.
research, I developed a mathematical model for dendritic crystal growth,
where a tree-like morphology develops at the solid-liquid interface at high
cooling rates that make plane-front freezing unstable. The ability to predict
the highly coupled solidification parameters such as the size, growth rate,
and chemical composition of a dendrite growing in a super-cooled liquid as a function
of the temperature difference is crucial to achieve desired microstructures
and, thus, material properties. My new dendritic-growth model went
beyond the existing models by calculating the interfacial driving force using
a thermodynamic-solution model and correctly relating it to the linear
kinetic theory. Compared to the existing models, this enabled it to
better predict the range of solutions for the temperature difference, at
which the transition from mass diffusion to thermal diffusion begins for the
material in particular, to achieve the desired material properties. I
developed an iterative algorithm to fit the thermodynamic model to empirical
solidification and thermo-chemical data and estimated the thermodynamic
parameters in solving the multivariate nonlinear system of equations, which
were incorporated into the new dendritic-growth model. While working towards
my M.S., I optimized the energy use of the drying unit of an operating paper
machine in collaboration with the paper industry. For this work, I was
rewarded with a research award by the Pulp and Paper Foundation of
Turkey. In addition to my research experience, I have also had the
opportunity to develop my teaching skills. During my studies at
Northeastern University, I have taught more than 450 students in the
Materials Science labs and received accreditations as well as university-wide
awards as a teaching assistant. I continue to teach many undergraduate and
graduate students in various Chemical Engineering topics at Hacettepe University
and mathematics related topics at the Turkish Military School. |
