Tosha Ashish Kalhan

Tosha Ashish Kalhan serves as a Research Fellow at the Saw Swee Hock School of Public Health, National University of Singapore (NUS), where she focuses on Type 2 diabetes complications through large-scale cohort studies. A dentist with over six years of clinical experience, she completed her PhD in Dentistry at NUS in 2021 after investigating oral-systemic disease links in pediatric populations.

Her academic qualifications include:

• Doctor of Philosophy (2021), Faculty of Dentistry, National University of Singapore, Singapore
• Master of Science (2016), Faculty of Dentistry, National University of Singapore, Singapore
• Bachelor of Dental Surgery (2008), K.M. Shah Dental College and Hospital, Gujarat University, India

Dr. Kalhan's research centers on cardiometabolic diseases and oral-systemic health integration, with specific expertise in atopic dermatitis, early childhood caries, and Type 2 diabetes complications. Her work examines how dental caries relates to systemic conditions like gestational diabetes and cardiovascular risk in children, leveraging large cohort studies to bridge dentistry and public health.

Her publications reveal a consistent interdisciplinary approach using epidemiological methods to explore oral-systemic connections. Key themes include caries risk prediction models for medical settings, eczema diagnostic criteria validation in children, and plaque pH analysis for caries relapse prediction. This body of work demonstrates how dental health metrics can inform broader systemic disease management, particularly in vulnerable pediatric populations.
