My name is Arghyanir Giri, I am a PhD candidate at the department of Architecture and Built environment TU Delft. I have done my Bachelors and Masters in Aerospace Engineering from IIT Kharagpur. I am 22 years old and I moved to The Netherlands from India this March for my PhD. I specialise in computational fluid dynamics (CFD) and during the pandemic, my focus of research pivoted from sustainable aviation to airborne transmission of pathogens as it was a concern that needed urgent attention and unfortunately even today it is a major cause of concern. The project was a collaboration study with scientists and aerosol experts about the interaction of pathogen-laden respiratory jets during a face-to-face conversation. Working with the PDPC on the frontrunner project 2 enables me to double down on this endeavor by collaborating with people from public health sector and pairing it with the power of numerical modelling that will lead us to profound insights and better public health guidelines.
