Sci Talk Topic: Mathematical legacy of Srinivasa Ramanujan: The man who knew infinity.​

Abstract: Srinivasa Ramanujan, known as “The man who knew infinity”, was a brilliant Indian mathematician. His life story is as interesting as his astonishing work in the field of number theory, especially on partition theory. We will briefly talk about his fascination in mathematics and present some amazing results from his so-called “Lost Notebooks”, with comments on their importance and implication toward modern mathematics and other sciences.​

Sci Talk Topic: Model-Centric vs. Data-Centric Machine Learning​

Abstract: Machine learning (ML) research has been model-centric for decades. That is, we consider ML modeling to be the heavy-lifting part requiring deep expertise to get it right. And the data preparation part is a tedious yet trivial job to complete as part of the pipeline. Although ensuring the data quality is understood to be a vital part of the pipeline, researchers often consider this part static. Once the data has been collected and prepared, we dedicate most of our attention to creating an accurate model. Data-centric AI challenges this concept in two different ways. First, it argues that many applications do not require a new model; the current off-the-self baseline suits the purpose. Second, it shows that effort spent on improving the data quality is more rewarding than improving the ML technique.
This talk presents research and development of data-centric machine learning and comprises the following topics. 
• First, I will outline recent works in Data-Centric ML worldwide. 
• Second, I will talk about the industrial and academic research we are conducting at VISTEC and how we plan to bring the benefits of data-centric machine learning to our society. ​
• Third, I will propose how model-centric and data-centric efforts can synergize.  
Finally, this talk will conclude with implications for students who wish to pursue a career in ML research and those who want to apply ML to solve their domain-specific problems.

Research:  In general, I am interested in Extragalactic astronomy, which means anything related to galaxies outside Milky way. The main theme of my research is galaxy formation and evolution. I use many world-class telescopes to observe galaxies at different epoch of the universe and study the physical process responsible for their evolution. Right now, I am focusing on the process of expelling hot gas out of the galaxies. It is of importance for the evolution of the galaxy itself and the chemical evolution of the entire universe.

Sci Talk Topic: Topics in Astronomy and Astrophysics​​

Abstract: I will start my talk with brief introduction of astronomy and astrophysics and how we as an observational astrophysicist do our jobs. I will introduce the entire process of doing research beginning with writing the research proposal to ask for the observing time at the telescope, talking about the journey to the telescopes and the observations, and finishing with the scientific process of analyzing data. To use the telescope, we need to apply for the observing time. Though the competitive rate depends on the telescopes, it is typically high. Moreover, the weather is also another factor that can fail our plan. After getting the data, we systematically select galaxies at different epoch of the universe by taking into account 3 main facts. First, the speed of light is constant, so light from distant galaxies takes time to reach us. The light we observe today is that emits from the galaxy millions or billions of years ago. Second, the universe is expanding. This causes the so-called cosmological redshift of the wavelength emitted from the galaxy. Finally, neutral hydrogen in the universe can absorb light at some particular wavelengths. Combining all facts, we can determine if the objects are really at the desired era of the universe.

Sci Talk Topic: Biodegradable polyesters: structural requirements and improvements

Abstract: Biodegradable polyesters are widely explored in both academic and industrial applications as attractive alternatives to non-degradable petroleum-based polymers. Polyesters such as polylactide (PLA) and polylactones are among the most well-known biodegradable polyesters due to their biodegradable and biocompatible properties and have been extensively employed in biomedical, agricultural, and food packaging areas. In this talk, key components for biodegradability will be discussed along with the future trends in polyester development.

Sci Talk Topic: Topics in Biology ​

Abstract:  Our research group are committed to cutting-edge scientific research and development of technologies for green chemistry, white biotechnology, biofuels, biorefinery, biosensors and bio-imaging. In this endeavor, we collaborate with several private sector entities in Thailand. We have also established a startup venture, Enzmart Biotech. Our current research can be classified into the following themes: Biocatalysis, Synthetic biology, Smart detection, and Enzymes structures and mechanisms. Biocatalysis is the use of enzymatic reactions to catalyze chemical reactions which can contribute to greener and cleaner chemical industries as well as to produce valuable and sustainable supply such as nutraceuticals and biopharma from agricultural waste and biomass. The enzymes being investigated in the research group include flavin-dependent oxygenases, halogenases, dehalogenases, oxidases, metaldependent oxygenases and aldolases, and PLP-dependent aldolases. Synthetic biology projects in our group constructs engineered cells or new metabolic pathways that are useful for turning “Waste to Value” or “Trash to Treasure”. Specific projects include Cell and Metabolic Engineering to convert organic waste from household and agricultural industries into biofuels such as propane, butane and gasoline. In smart biodetection, we have developed bioreporting technologies based on enzymatic reactions of luciferases or enzymes that can emit blue, green or orange light. These reactions can be used as in vivo cell monitoring tools for specific gene or disease detection in experimental animals. We also have developed proprietary technology that can be used to detect toxic compounds such as pesticides or herbicides contaminated in agricultural products and in environment. Enzymes structures and mechanisms involve discovering frontier knowledge to support technology development. Our research group has long been recognized for our pioneer work in discovery of in-depth understanding of the reaction mechanisms of selected redox and aldolase enzymes. We use multi-disciplinary approach and a wide range of physical and biochemical tools and techniques such as transient kinetics, spectroscopy, structural biology and computational chemistry for studying enzymatic reactions.
