Lab leader

Dave Smith
Assistant professor of science, YaleNUS CollegeLab member since 2016.
I'm an applied mathematician studying boundary value problems for linear equations. I run the unified transform lab at YaleNUS College. I received my Master’s degree in Mathematics from University of York, United Kingdom, in 2007 and my PhD from University of Reading in 2011. Before joining YaleNUS College in 2016, I was a postdoc at Universities of Michigan, Cincinnati and Crete. When I'm not doing mathematics, I'm usually tinkering with computers or listening to heavy metal with my cat, Oreo.
I supervise all the projects in the lab.
I contributed to outputs [NS2024a], [ABS2022a], [AS2019b], [AS2019a], [ST2022a].

Michelle Ong
Undergraduate student, YaleNUS CollegeLab member since 2022.
I'm from the class of 2024. I started college thinking I would major in physical sciences, but I was drawn to mathematics after taking a couple of calculus classes. I'm intrigued by how mathematical concepts can connect fields and problems that seem to have nothing else in common. Outside of maths, I love all aspects of language, and I'll probably end up with a literature minor.
I completed the project D to N maps for the heat equation in cylindrical coordinates in summer 2022.
I contributed to output [Ong2022a].

Graduate, YaleNUS CollegeLab member 2019–2020.
I’m a graduate of YaleNUS College, from the Class of 2020, and will be starting a PhD in Mathematics at Drexel University in Philadelphia, USA. My primary interest is in PDEs, though I’m intrigued by complex analysis and probability. Outside of mathematics, I enjoy reading Russian classics, watching singing competitions and drawing various objects.
I completed the project UTM as diagonalization of multipoint differential operators in summer 2020. I completed the project Generalized Fourier series methods using ApproxFun in the semesters 2019–2020. I completed the project Adjoints of general multipoint differential operators in summer 2019.

Kshitij Bansal (Stitch)
Graduate, YaleNUS CollegeLab member 2021.
I'm from the Class of 2020, and am graduating from a MSc (Econ) from the LSE this year, and I had the same major while at YaleNUS. I've always had a soft spot for Mathematics, and taking OPDEs under Prof Dave was my gateway drug. I'm quite interested in learning about these problems and applying them to novel economic models that have been simplified thus far. It's great that most of economics has always borrowed its methods from the physical sciences and maths, and I'm just hoping to be a small part of that. When I am not stuck in these issues, I am usually either playing Forza 4 Horizon on my AliExpressimport budget gaming PC, or trying to figure out what exactly Elon wants from his CarbonCapture XPrize.
I completed the project Transform method for variable coefficient PDE in summer 2021.
I contributed to output [Ban2021a].

I'm from the Class of 2021 (formerly 2020) and major in Mathematical, Computational, and Statistical Sciences. My academic journey at YaleNUS has been a long road converging towards Applied Mathematics: from Economics to Philosophy to Finance to Financial Mathematics to Data Science to now, finally, Applied Maths proper, with plenty still left to learn. I'm interested in taking the lessons of Applied Maths to make more rigorous models and arguments in the realms of finance, economics, and public policy.

Keertana Veerayah
Undergraduate student, YaleNUS CollegeLab member 2022.
I am an undergraduate student at YaleNUS College. I am in the class of 2024, with a major in Mathematical Computational and Statistical Sciences (MCS). Applied mathematics is a field that has always appealed to me as I find it deeply fascinating how abstract mathematical concepts can be used to explain and understand realworld phenomena or logical problems. I particularly enjoy the creativity that comes with communicating mathematics, via written or verbal works. Beyond my academic endeavours, I enjoy the outdoors, teaching children and playing squash.
I completed the project Nonlocal D to N maps for the heat equation in summer 2022.

Wang Yanhua
Undergraduate student, YaleNUS CollegeLab member 2020–2022.
I am from the class of 2022 at YaleNUS College. In early 2020, I've done some research using computational geometry to predict animal locomotion, and I've also dabbled in journalism at the Straits Times. Earlier in freshman year, I picked up contract bridge and fell in love with it; I thought studying Mathematics would be helpful for playing the game, but it turns out I needed a peaceful and focused mind as much as an analytical mind (watching Avatar's Uncle Iroh is helping me with that). When I am not watching Netflix, I enjoy cooking new dishes and hanging out with my dog.
