Education Post-Doctoral Fellow,Harvard University. 1999 - 2001 Ph.D., University of California at Berkeley. 1994 - 1999 5-yr integrated M.S., Indian Institute of Technology (IIT), Kharagpur. 1989 - 1994 Research Interests The Gracias laboratory develops new methods to fabricate very small devices and integrated structures, and characterize these systems using microscopy and spectroscopy. A major thrust of our research is focused on constructing miniaturized 3D devices which are especially challenging to fabricate at small size scales. We are also particularly interested in understanding, synthesizing and characterizing self-assembling, intelligent and hybrid biotic-abiotic systems. We utilize a range of experimental techniques including photo-, e-beam and nano-imprint lithography; thin film deposition, molding, etching, culture of prokaryotic (E coli) and eukaryotic (e.g. fibroblasts, islets, myoblasts) cells, biological assays (e.g. fluorescent stains, ELISA, cytology), non-linear optical spectroscopy, electron microscopy (TEM & SEM with fixation), RF measurements such as GHz spectrum analysis, electrochemical methods such as potentiometry and chronoamperometry and four point electrical testing with femto-amp resolution. We also utilize analytical methods as well finite element methods (HFSS, Surface Evolver, COMSOL) to model data. Our lab is multidisciplinary and students in our lab have had backgrounds in Chemical and Biomolecular Engineering, Electrical Engineering, Physics, Chemistry, Materials Science, … Continue reading →

Research Interests Currently, Parwezs research activity is focused finding new approaches to manage corneal disease. Corneal infections are a major cause of visual impairment worldwide. In the UK alone, 6000 patients are affected from corneal microbial infections every year. Bacterial organisms such Pseudomonas aeroginosa are major causative agents in pathogenesis. Visual impairment often is very rapid (within 24 hours) and frequently leads to permanent visual loss (Figure 1). A common problem during such infection is the severe levels of corneal tissue damage. We know from animal models, that this results from the combined effects from the actions of the pathogen and the hosts inflammatory process. The cornea quickly loses its normal transparency, leading to visual impairment. Since the cornea is a thin structure (human central cornea thickness is only 550m), tissue damage carries high risks of ocular perforation and visual loss. Although antimicrobial therapies are usually successful in reducing the pathogen load, they do not help to limit tissue damage. Currently, there is no effective treatment to limit this. Such therapies are highly desirable since patients would benefit from reduced effects of uncontrolled tissue damage. Parwez has set-up a clinical and laboratory investigative programme, to investigate how different pathogens interact … Continue reading →
