He has since worked in A*STAR, focusing on quantum photonics and quantum sensing technologies. He is a recipient of the A*STAR National Science Scholarship and the A*STAR Graduate Scholarship. He is fond of music (but is rubbish at making any), and is convinced that cat videos are the true purpose of the Internet.


Dmitry Kalashnikov, PhD


Dr. Dmitry Kalashnikov received his Master and Ph.D. degrees in 2006 and 2009, respectively, from Kazan (Volga region) Federal University (former Kazan State University), Russian Federation. Since 2009 he has been working in A*STAR as research scientist in Data Storage Institute (2009) and Institute of Materials Research and Engineering (2018). His areas of research are quantum optics and photonics, single photon emitters, and integrated optics. Currently he is focused on the interfacing of single photon emitters from 2D materials with photonic structures on chip. His hobbies are reading history and science-fiction books, playing football, cooking nice food, and brewing beer.


Anna Paterova, PhD


Dr. Anna Paterova received her undergraduate degree in 2014 from Lomonosov Moscow State University. She later moved to Singapore to start a PhD with the support of the SIPGA A*STAR and SINGA A*STAR scholarships. From 2014 to 2018 Anna was doing joint PhD research related to quantum optics and interferometry in Data Storage Institute, A*STAR and Nanyang Technological University. She successfully defended her PhD degree in 2018 at Nanyang Technological University on the topic “IR metrology using visible light”. Since receiving her PhD, Anna has been a research scientist in the Institute of Materials Research and Engineering at A*STAR. Currently, her research interests focus on the field of quantum interferometry and its applications. Beside her research she loves playing volleyball and reading books in her spare time.


Hongzhi Yang, PhD

Senior Specialist

Dr. Yang Hongzhi received his master's degree in laser optics from Shandong University, China in 2007. In 2012, he received his PhD degree in nonlinear optics from the physics department of the National University of Singapore. His current research interest includes optical measurement and instrumentation, IR imaging and spectroscopy. During his leisure time, Hongzhi enjoys reading, watching movies, listening to music, and traveling.


Junyi Lee, PhD


Dr. Junyi Lee received his B.A. in physics from the University of Chicago in 2012 and went on to pursue his Ph.D. in physics at Princeton University under the tutelage of Professor Michael Romalis. During his time at Princeton, Junyi worked on a project he affectionately named the Spin-Mass Interaction Limiting Experiment (SMILE), which improved the best laboratory limits of the (hypothetical) axion’s anomalous coupling to nucleons by an order of magnitude over two decades of axion mass range using a K-3He co-magnetometer and two slabs of 250 kg Pb weights. Junyi is currently interested in applying spin-squeezing techniques to improve the sensitivity per unit volume of scalar atomic magnetometers operating in geomagnetic fields, and he is also separately leading an effort to harness quantum computing for the optimization of non-linear optical elements. In his spare time, Junyi enjoys being out in the mountains hiking, camping, or skiing – assuming he gets there without misplacing his car keys first!


Aravind Padath Anthur, PhD


Dr. Aravind P. Anthur obtained his PhD from IIT Madras, India in the year 2014 in the field of nonlinear optics and optical communication. He then worked in the optical communication industry in India before moving to Dublin, Ireland for post-doctoral research studies in the area of high speed optical communication systems based on optical comb sources and novel lasers. He later joined A*STAR to work on integrated non-linear optics that aims to make highly efficient non-linear devices for various applications like sensing, quantum optics and quantum communication.


Desmond Toa Zi Siang, PhD


Dr. Desmond Toa completed his B.A. in Physics from UC Berkeley and Ph.D. in Chemistry from Princeton University in 2011 and 2019 respectively. At Princeton, his main research revolves around vibronic quantum coherences in algal light-harvesting complexes using ultrafast two-dimensional electronic spectroscopy and quantum chemical simulations under Prof. Gregory Scholes’ supervision. His current research interest involves the following two topics: (1) spontaneous parametric down-conversion from aperiodically-poled nonlinear crystals and (2) expanding end-user applications in the chemical and biomedical industries for our quantum hyperspectral microscopes. He enjoys meditating, reading random pieces of knowledge, especially those pertaining to CPU design, and Chinese novels.


Prithvi Gundlapalli, BSc


Mr. Prithvi Gundlapalli graduated with a BSc (Hons) in Physics from the National University of Singapore in 2020 and will be commencing an MSc Eng in Physics and Nanotechnology with a specialisation in Quantum Engineering at the Technical University of Denmark in 2021. He has done various research attachments and his bachelors thesis at the Institute of Materials Research and Engineering, A*STAR, where he worked on quantum sensing with nitrogen vacancy centers in diamonds. He is currently a research specialist at the Institute where he is working on chip-based single photon detectors. His research interests are mainly in quantum sensing and in developing its practical applications. His hobbies include DJing, cycling, and playing with the numerous stray cats around his area, as well as convincing people that cats are better than dogs.


Cleaven Chia, PhD


Dr. Cleaven Chia graduated with a BSc in Physics with Theoretical Physics from Imperial College London in 2014, and a PhD in Applied Physics from Harvard University in 2021. During his PhD, he worked under the supervision of Prof. Marko Loncar to develop a coherent spin-phonon interface between localized phonon modes in phononic crystals and spins within silicon vacancy centres in diamond. Cleaven's current research interests lie in developing hybrid quantum systems and quantum sensors that interface photons, phonons, and spins. He also has experience with Lumerical FDTD and COMSOL simulations, diamond nanofabrication, and fibre optical characterization. Outside of research, Cleaven follows Formula 1 and football (supporting Manchester United FC), and is also a fan of the band Muse.


Di Zhu, PhD


Dr. Di Zhu received his Ph.D. (2019) and M.Sc. (2017) from Massachusetts Institute of Technology, and B.Eng. (2013) from Nanyang Technological University, all in Electrical Engineering. From 2019 to 2021, he was a postdoctoral fellow at Harvard University. His Ph.D. thesis with Prof. Karl Berggren focused on superconducting nanowire single-photon detectors, and postdoc research with Prof. Marko Lončar centered around thin-film lithium niobate photonics. He was a recipient of Harvard Quantum Initiative Postdoctoral Fellowship, A*STAR National Science Scholarship, and MIT Jin-Au Kong thesis award. His current research interests include integrated quantum photonics, applied superconductivity, and nanoscale electromagnetics. Outside of research, Di enjoys reading and hiking.
