Bio:  My first  post-doctoral training was on fabrication of micro and nanoparticles at  University of Campinas in Brazil in 2008. At the end of 2009 (2009-2015) I  joined Prof. David Weitz’s group at the School of Engineering and Applied  Sciences at Harvard University where I studied fabrication of functional  materials at interfaces, structural emulsions, encapsulation of ingredients and  controlled release systems using drop-based microfluidics as well as  conventional microencapsulation techniques. Currently, I am Assistant Professor  of Food Chemistry and Ingredient Technology at Cornell University, Department of  Food Science (2015-present). I lead a group of 42 Ph.D. and Post-Doctoral  scientists and I am co-author of 126 peer-reviewed publication and 19  provisional/granted patents.

Abstract: In the  first part of my talk, I will focus on using emulsion drops generated in  microfluidics as templates to fabricate functional polymeric microcapsules and  microparticles that respond to a range of environmental stimuli in prescribed  ways. In addition, taking advantage of material behaviors at liquid-liquid  interfaces enables engineering complex soft materials and encapsulating a wide  variety of actives including colorants, vitamins and biocides. I will discuss  few examples of encapsulation and triggered-release systems developed for  different applications including chemical, pharmaceutical, and food industry. In  the second part of my presentation, I will demonstrate how we can utilize  different geometries and fluid mechanics in microfluidic channels for detection,  and collection of biological samples such as small molecules and bacteria in  liquids, study antibacterial resistance, and separate motile sperm in semen  samples for in vitro fertilization application (IVF). Finally, I will  share with you our microfluidics-based 3D-Gut-on-a-Chip device and bioreactors  designed for screening bioavailability and toxicity of different  ingredients.
