Interests
The cells of our body contain a circadian clock mechanism that plays a vital role in coordinating physiological processes and the dysfunction of which is linked to disease. Timing ques, known as Zeitgebers, set the time of the circadian clock and maintain cell synchronicity. My research examines novel zeitgebers and how zeitgebers can be applied to sustain robust circadian rhythmicity in vitro. The aim is to better recapitulate physiological processes in organ on a chip systems.Publications
