Late posting. Been super busy in this challenging and constantly changing time.

Congratulations to Hang Li, the highly productive student who works very hard on this project, and has also submitted his thesis and becoming a dad earlier this year.  
Check out the paper describing a highly unusual molecule made by a highly unusual NRPS "Biosynthesis of a New Benzazepine Alkaloid Nanangelenin A from Aspergillus nanangensis Involves an Unusual l-Kynurenine-Incorporating NRPS Catalyzing Regioselective Lactamization"  https://doi.org/10.1021/jacs.0c01605

Congrats to Hang Li and Haochen Wei (ANU) for uncovering new phytotoxic cytochalasans from the wheat pathogen Parastagonospora nodorum that facilitate disease development and for the work accepted in ACS Chemical Biology. Another great collaboration with Peter Solomon (ANU), Keith Stubbs (UWA) and Ern Lacey (MST).

Our lab welcome Marianne Costa this week. Dr Costa won a CSIRO FSP SynBio Fellowship and is joining the Chooi lab to start his research on engineering bacterial PKSs. 

Marianne hails from the UK and did her PhD under the guidance of Prof Greg Challis at the University of Warwick.

She will be collaborating with her CSIRO mentors Dr Maciej Holowko and Dr Louise Thatcher in her research project.

Congratulations to Jinyu, the 1st PhD student of Chooi lab, for his paper published in the prestigious Journal of American Chemical Society. Hang Li, another PhD student, is also a co-author on this paper.

Please check out the work titled "Fungal Dirigent Protein Controls the Stereoselectivity of Multicopper Oxidase-Catalyzed Phenol Coupling in Viriditoxin Biosynthesis" at https://pubs.acs.org/doi/10.1021/jacs.9b03354


Welcome Thom Booth!

Dr Thom Booth has joined the Chooi lab and started his research on a project funded by CRC-P in collaboration with Microbial Screening Technologies (microbialscreening.com), Dr Andrew Piggott at Macquarie University and Advanced Veterinary Therapeutics. 

Thom hails from the UK and did his PhD under the guidance of Prof Barrie Wilkinson at the John Innes Centre, Norwich.

His research will focus on genome mining of Australian actinobacteria to uncover new antibiotics.

2019 Update!

Finally, get to update the Members page of the website (procrastinating from doing what I supposed to do).

At the end of 2018, we farewell Nico who have been with us for eight months under his CEPAS Exchange Program Fellowship from the Brazilian Government. It has been fun and productive. Hope he could come visit us again, we missed you Nico!
We also congratulate our graduated Masters and Honours students (Fiona and Sarah) who got a job last year, and most recently being Ronan who just joined Proteomics International early this year! 
Also big congratulations to Coco Xie who did her Master project in Chooi lab and obtained an RTP Scholarship.
At the beginning of 2019, we also welcome Susan Lean, who is an RTP scholar as well.

Look forward to another fun, fulfilling and productive year ahead!

Tribute to the magnificient Moreton Bay fig tree at UWA campus

posted Nov 22, 2018, 7:00 AM by Yit Heng Chooi

Sad that the far-reaching branches of the giant Moreton Bay fig tree (Ficus macrophylla) that made the banner of this website has partially collapsed.


Hope we could save the remaining of the tree. Time to think about how to support other branches on this tree.
