Mr Lance has over 25 years' experience in Asian financial markets and his primary responsibility will be to lead the relationships with Ascalon's partners in Australia.
Before joining Ascalon, Mr Lance was based in Hong Kong as CEO and founder of head fund DragonBack Capital.
He will be based in Sydney and will report to Ascalon Capital Managers chief executive Chuak Chan.
Mr Chan said of the appointment: "He is a strong and dynamic addition to our team at a time when Ascalon continues to grow."
The appointment comes on the back of Ascalon's aggressive Asian expansion plans, following last month's acquisition of a 30 per cent stake in Singapore-based alternative manager, RV Capital.
