Biographical details

Taz has Bachelor degrees in Forest Science (Hons) and Science from the University of Melbourne (1999). After working as a Forest Ecologist for a couple of years she returned to the UoM to complete a PhD titled “Photosynthetic responses to light, nitrogen, phosphorus and pruning of Eucalyptus in south-eastern Australia” under the supervision of Prof Mark Adams and A/Prof Charlie Warren (2006). 

Taz has been a tree physiologist since then, first as a post-doc in Tree Physiology at the University of New South Wales (UNSW) and since 2008 as a Research Fellow in Eco-physiology at the University of Sydney.

Research interests

Tarryn (Taz) works out in the bush, predominately on Eucalypts; examining physical, chemical and physiological mechanisms Australian native trees employ to grow in such a dry, bright environment. This position has allowed her to work in forests managed for a range of purposes all over Australia. Most recently Taz has been working on the influence of tree and leaf structure on processes of photosynthesis and transpiration by eucalypts that regenerate from fire by sprouting.

Taz’s specific research foci include:

  • Quantifying carbon gain and water loss by eucalypts that regenerate from fire by sprouting;
  • Assessing the ubiquity of photosynthetically active radiation (Q) being only ‘visible light’ amongst Australian native plants of different life forms;
  • Determining what physiological traits these plants must exhibit in order to use wavelengths not included in Q for photosynthesis;
  • Examining the influence of chemical, structural and physiological features on within-leaf light environment and photosynthesis.

Teaching and supervision

Taz’s currently lectures on Forests and Fire for AGEN1002 Sustaining our Landscapes and coordinate the research field excursion for that subject; and has provided guest lectures on Nutrients in Australian Forest Ecosystems for PLNT2003 Plant Form and Function since 2008.

Taz has successfully co-supervised two Honours students at UNSW (both graduating with first-class honours) and is currently co-supervising two PhD students at the University of Sydney.
