Physiomics plc, a mathematical modelling, data science and biostatistics company supporting the development of new therapeutics and personalised medicine solutions, has announced the promotion of Jesse Thissen to the position of COO.

Activist investor Mike Whitlow was appointed executive director of the listed firm recently after more than three-quarters of shareholders voted to remove former chair Dr Jim Millen as part of a wholesale replacement of the board.

The firm says Thissen has served as head of biometrics and has played an instrumental role in strengthening the company’s operational capabilities, technical leadership and project delivery.
