Pathological biomineralizations such as breast cancer microcalcifications, kidney stones, and cardiovascular calcifications are not well understood, especially from a materials science perspective. Previously, in collaboration with the Fischbach lab in the Cornell Biomedical Department, we have shown that biomineral materials properties (crystallinity, size…etc) greatly impact cellular interactions and can often be correlated with the severity of pathology. My research will continue projects focused on both thorough characterization of pathological biomineralizations and subsequent informed biomimetic synthesis for use in cell-mineral experiments.

Osteocytes, the most abundant bone cells, which derive from osteoblasts during bone formation, create dendritic processes providing a dense network of about 74 km per cubic centimeter in human osteons, and a surface of about 215 square meter in the human body. This huge accessibility to bone matrix offers facilitated mineral transport through bone tissue, and consequently, active control of mineralization.

In my PhD, I studied the role of osteocyte network in early mineralization of human bone during remodeling using focused ion beam-scanning electron microscopy (FIB-SEM). Now, in collaboration with Fischbach and Wiesner labs, I aim to shed light on the interrelationship between the osteocytes and cancer cells in the metastatic sites of bone, by using additional high-resolution techniques, such as optical super-resolution microscopy and nano-CT.

Chris is a joint postdoc between the Estroff group and the Marohn group in the Chemistry and Chemical Biology department. His research focuses on metal halide perovskites for solar applications. Specifically, he is working to better understand how processing conditions affect the morphology, crystal texture, and other properties of blade coated thin films and how these changes affect the resulting optoelectronic properties of the films.

My primary research interest is studying biological materials involved in pathological mineralization, particularly the matrix-mineral interactions of calcifications found in breast tumors. I aim to use Raman spectroscopy and (cryo) electron microscopy to study the tumor microenvironment and understand the role that calcifications play in the growth and spread of breast tumors.

I joined the group in fall 2021 as a Ph.D. student in MSE. I'm working in the Perovskite Project, which is funded by DOE, and collaborated with many research groups and national labs. My research focuses on using in-situ AFM and NMR to study the mechanism of growth of perovskite crystals and solution chemistry.

My research stems from an interdisciplinary collaboration with the Cornell Lab of Ornithology which aims to link evolutionary changes in melanogenesis in feathers to internal feather structure, and study the implications of feather structure on the quality and longevity of flight feathers. My current techniques of focus are scanning electron microscopy (SEM) and nanoscale computed tomography (NanoCT).

The research topic I'm currently working on is investigating the nonclassical coccolith formation mechanism under synthetic experimental conditions. By studying chemical interaction between patterned organic baseplates (made by micro-contact-printing SAMs) and macromolecule-modified coacervate attachments, we expect to control calcite nucleations at specific sites on interphase under laboratory conditions.

My current research investigates the biomineralization found in diseased human aortic valves by using Raman microscopy and histology. The focus of this project is mapping mineral with various organic matrix species using metrics such as the spatial address of the mineral in the valve. We can better understand how these characterization techniques complement each other and identify further regions of interest for Raman study.
