Karthika earned a Bachelor of Science in Food Technology and Nutrition from the Royal Melbourne Institute of Technology (RMIT) University (Australia) and completed a Master of Science in Nutrition and Dietetics from New York University (USA).

After her education and experience in Australia, Karthika moved to the United States in 2013. She completed her supervised clinical practice through Commonwealth Health Systems in Pennsylvania and began practicing as an outpatient oncology dietitian at New York City Health and Hospitals system’s cancer centre. During her time in New York, she served as a member of the Commission on Cancer. In 2018, she returned home to Singapore and joined Tucker Medical.

Karthika’s professional passion is to help patients and families achieve their health goals through practical, culturally-appropriate and individualized action plans. While advocating personal and flexible nutrition interventions, she utilises technology to define patients’ baselines and monitoring of their progress. At Tucker Medical, she is heavily involved in nutritional metabolic therapy for cancer patients, both during active treatment and for prevention.

Karthika also works with patients and families in areas outside of cancer care. She has experience in supporting disease reversal in conditions such as diabetes and prediabetes, fatty liver disease, and metabolic syndrome. She endorses an extensive use of nutritional interventions across the spectrum from low-carb and ketogenic diets to low-fat and vegetarian/vegan eating styles. As a Singapore local, from an ethnically Indian background, and with training and practice in the US, she understands and applies the appropriate cultural, religious, and emotional landscape of nutrition and dietary management.

During her free time, Karthika enjoys sports and physical activity. She enjoys hiking, travelling, running and exploring new restaurants. She is an ardent fan of the Arsenal Football Club and can be found watching almost all of their games.
