Ph.D. Student

LinkedIn, Google scholar

Shruti Choudhary received her B.E. in Electronics and Telecommunication Engineering from Army Institute of Technology (AIT), Pune, India in 2018, where she researched on improving supercapacitors' energy density performance in addition to working at the AIT robotics club for 4 years. After graduating she interned at the Indian Institute of Technology, Indore to work on the synthesis of metal oxide-based material for supercapacitors.  She then worked as a consultant at Washington University in St Louis and the Government of Delhi, India for one year where she worked on the Project Real-time pollution source apportionment study of Delhi City. She obtained her master's in Energy, Environmental, and Chemical Engineering from Washington University in St Louis in 2021 and moved to the University of Miami to continue her Ph.D. research work at the Aerosol and Air Quality Research Laboratory. She has worked on many collaborative projects with Washington University School of Medicine, St. Louis University Center for Advanced Dental Education, St Louis Children's hospital, St. Louis Symphony Orchestra, The MUNY, and, Applied Particle Technology, Inc.

Airborne transmission of infectious diseases in health care and public settings  

   

Choudhary, S et al. (2021) AAAR 2021; 
Choudhary, S et al. (2021) J. Infection Control & Hospital Epidemiology.

The work focusses on airborne transmission of COVID19 in various health care settings such as dental settings, intensive care units and Emergency department in collaboration with Washington University School of Medicine, St Louis University Center for Advanced Dental Education and orchestra settings in collaboration with St. Louis Symphony Orchestra and The MUNY.
Performance of a ventilated chamber for low-cost PM sensor calibration

  

 Zhang et al. (2021) J. Aerosol Sci.151, 105680

Particulate matter (PM) sensors are popular for distributed monitoring due to their portability, low-cost and networking capabilities. To provide reliable data, these sensors have to be calibrated periodically in the laboratory. This is often done in chambers with several of them co-located, alongside several research grade instruments. It is important to confirm that the aerosol is well distributed to ensure reliability and accuracy of the calibration tests. A computational fluid dynamics (CFD) model including effects of turbulence and Brownian motion is used to predict particle trajectories and distribution in the chamber. 

 

While many low-cost particulate matter sensors measure air quality on a spatiotemporal scale, we are now working on integrating these sensor with the technology for COVID-19 detection with the end application being deployment of these integrated sensors in many settings such as health care settings, public places.

Real Time Source Apportionment of Delhi

Air Quality is a global challenge and face daunting challenges when it comes to controlling the pollution and reducing the well known health impact and climate change. It is important to identify the major sources of air pollution and develop strategies to mitigate them. An air quality monitoring network has been setup in the National capital territory of Delhi, India to identify major sources contributing to pollution on real time using cloud based approach. Furthermore, real time chemical speciation monitors were installed to provide elemental composition (Metals, Elemental carbon, Organic carbon)
