Welcome to the Mutwil Lab!
​The Mutwil lab is located within the School of Biological Sciences at Nanyang Technological University, Singapore.
We use systems biology to elucidate the function of genes in the plant kingdom. Today, knowledge of gene function is mostly confined to Arabidopsis thaliana, the main model organism in plant research, which limits our understanding of the plant kingdom. To remedy this, we are characterising also other plant species in terms of genomics, gene expression, metabolomics and protein-protein interaction networks. Based on this biological data we can then predict gene function with state-of-the-art network ensemble methods and other dry-lab techniques. This knowledge is important to understand plants and to tailor them to our needs.

End of 2020!

Finally, this bizarre year is coming to an end. The lockdown and staggered working hours have thrown a wrench into our daily routine, but thanks to the computational aspect of our work, we still managed to do research. Here is what happened in 2020:
1) Despite the lockdown (April-June), our lab managed to produce six papers (2 reviews and 4 original research) this year.
Picture
2) Another batch of students graduated from BS1009 - Introduction to Computational Thinking, armed with a solid foundation in Python programming and algorithm development. This year, we had an unusual project for the students: to analyze >20,000 RNA sequencing experiments of pathogenic bacteria, and to identify novel genes that are putatively involved in protein synthesis. The results of the project were published in BMC Biology, and you can read more about our pedagogical adventure here: Strength in Numbers: Research Amidst a Pandemic. ​
Picture
3) 23 of the BS1009 undergrads did a two month-long internship in our lab to construct an online database www.fungi.guru. The project is building upon the BMC Bio paper, as the students analyzed >40,000 RNA sequencing samples from the fungi kingdom, and collectively wrote and published a paper. The results have been published in Computational and Structural Biotechnology Journal and our journey is described in this article:  Approaching New Frontiers in Fungi Research.

4) Devendra got a lucrative offer from ACM Biolabs Pte Ltd, working there now as a Scientist since September, while IngTsyr moved to Yongui Gao’s lab to continue as Project Officer. Well done, both, and see you around the campus!
​

5) The lockdown restlessness caused Marek to build ChuckNorris, a very cost-efficient (<4000$) workstation with 64 cores (128 threads), 256 GB RAM and 16 TB storage. You can read more about the assembly process here.

6) Marek served as a main PhD opponent for Dr. Chanaka Mannapperuma (11.06.2020) and Dr. Bastian Schiffthaler (12.06.2020). Swedish PhD defenses are quite different from the German or Singaporean defenses, as i) the ‘opponent’ needs to make a small presentation introducing the thesis and ii) the ‘opponent’ and ‘defendant’ should discuss for 1 hour in front of the audience. Pretty hardcore! 

7) Three URECA students joined our lab: Erielle Villanueva, Dhira Putri and Wu Jingyuan, to work on organ-specific co-expression, soil metagenomics and a new search engine for scientific articles, respectively. 
​

8) Together with Asst. Prof. Adriana Lopes dos Santos, we obtained a collaborative research award to work in single-cell transcriptomics of algae. We are looking for a motivated Project Officer/Research Associate to work on this project.

9) We have two Postdoc positions, and one Project Officer position open. Check out the Openings section.

Time flies and the the two PhD students did a good job defending their projects and work. Jonathan talked about his project that uses machine learning to identify genes involved in secondary metabolism, while Qiao Wen described her systems biology analysis of heat acclimation project. Good job!

It has been a while since the last update and a lot of good things happened. 

1) We had a pleasure to host four fantastic Final Year Project (FYP) students for three months.  Ying Kiat (nr. 1 from the left) and Vernice (3) were supervised by Dr. Devendra Shivhare (2) and Dr. Zhu Xinyi (SCELSE, not shown), and have identified many plant extracts that inhibit planktonic and biofilm growth of Pseudomonas ​aeruginosa and Staphylococcus aureus. Mun Yi (4) and Veronique (6) were supervised by Qiao Wen Tan (5) to study stress memory and cross-acclimation to multiple abiotic stresses in Arabidopsis thaliana​. 
Picture
2) The group expanded. Dr. Irene Julca and Dr. Riccardo Delli-Ponti joined to work on the Hedyotis genome project and on an online database capturing expression of biosynthetic pathways, respectively.
Picture
3) We finished coordinating the first run of Computational Thinking course (BS1009). Now ~230 students are (theoretically) able to write useful scripts in Python. It was a great experience and we look forward to do it again next year. ​
Picture
4) We got some papers out this year and produced two comparative transcriptomic databases: malaria.tools allows comparative genomic and transcriptomic analyses for Plasmodium species, while diurnal.tools can analyse diurnal gene expression in 17 members of Archaeplastida, including  algae and land plants. Diurnal.tools lands in research highlights in Plant Cell and Physiology.

5) Devendra, Irene and Marek attended a bryophyte workshop in Melbourne in December. It was good to catch up on Marchantia research and hang out with Prof. Dr. Staffan Persson!

The year of the pig started well!
  1. I am very proud to say that Camilla Ferrari, my Ph.D. student from Max Planck Institute of Molecular Plant Physiology, defended her Ph.D. thesis with a very strong magna cum laude. Congrats to Camilla!
  2. Camilla's Ph.D. work culminated in a publication in Nature Communications (please check out the publications section). Further congrats, Camilla!
  3. We have been successful in securing a Tier 2 grant to study the biosynthetic pathways of Hedyotis corymbosa, which as potent growth inhibition activity against several forms of cancer. We will sequence and assemble the genome, generate transcriptomic and metabolomic atlas and identify the active compound by a combination of biophysical and in vivo approaches.
