About
I am a behavioral ecologist and ecophysiologist specializing in studying the plasticity of reproductive behavior and life-history strategies in animals in response to a changing world, encompassing both social contexts and physical environments. I completed my PhD at the Australian National University in 2023, investigating the short-term plasticity and long-term costs of male reproduction and the effects of early-life environment stress on subsequent adult behaviour, growth, reproductive output and lifespan. During my doctoral studies, I received support from the Australian Government Research Training Program International Scholarship, the Fee-Offset Scholarship, and a Taiwanese Government Scholarship to Study Abroad.
Currently, I hold a postdoctoral research position at ANU, where I collaborate with Prof. Michael Jennions and Dr. Megan Head.

Research interests
My research primarily focuses on fish, including:
(1) Short-term reproductive plasticity
- Can males increase their sperm production when more females are present in their vicinity?
- Can males control the timing of sperm release using their intermittent organ?
- Do animals modify their nest design (location, structure, material) and nest-building behaviors based on ambient conditions such as water velocity?
(2) Long-term reproductive costs
- Do mated individuals experience accelerated aging and reduced lifespan compared to virgins?
- Which reproductive components are more costly for males: mating behaviors (courtship, male-male fights) or gamete production (ejaculation, sperm traits)?
(3) Effects of environmental stress on life-history trajectory
- How do freshwater fish adjust their life-history strategies when living in a salinized aquatic environment?
- When adaptive plasticity relies on stable environmental cues, how do animals adjust their growth, body condition, and reproductive investments in response to fluctuating environmental conditions such as salinity?
- Does reduced food availability impact an individual's ability to cope with other environmental stresses, such as high temperatures?
