Dr Jing (Maggie) Chen holds BSc in Computer Science from the Lanzhou Jiaotong University, China, MSc in Finance & Investment Management and PhD in Finance from the University of Aberdeen, UK (2011).

Prior to coming to the UK, Dr Chen worked at China Telecom and Dell (China) ltd. She started her business career as a computer software engineer, specialising in programming and system design before moving into company management and subsequently, pursuing an academic career in finance and investment. From September 2010 to August 2015, Dr Chen has been a lecturer and senior lecturer in the School of Management at Swansea University and senior lecturer in financial mathematics in the School of Mathematics at Cardiff University afterwards. During the 2014/2015 academic year, Maggie holds visiting/adjunct professorship in the Statistics Departments in both the Columbia University (New York City) and University College London.

Maggie’s main research focus is on liquidity provision, information dynamics and their relation to policy changes in financial markets. To date, her research agenda has focused on modelling the effect of various liquidity measures on trading decisions in different segments of financial markets in both developed countries (e.g., the UK) and emerging economies (e.g., China). Recently, this research has mainly focused on applying Hawkes processes to model jumps in financial markets. The overarching goal of the research agenda has been to obtain more robust and powerful empirically derived measures of liquidity utilising market microstructure theories drawn from the academic finance literature. She anticipates that this area of research activity could help investors, analysts, regulators and others to better assess information on market liquidity, and so more effectively predict future prices and trades. The applications of Hawkes types of models can also be extended to users in other industries such as insurance, into which industry Maggie has invested time and effort to form good understanding.

Dr Chen has built-up an international research profile by publishing her work in leading academic finance journals. Her work has appeared in esteemed international scholarly journals including the Pacific Basin Finance Journal, European Journal of Finance, Journal of Economics Behaviour and Organisation and Journal of Forecasting. Additionally, her study on the link between CDSs and the current Eurozone sovereign debt crisis has been cited in the House of Lords and the Organisation for Economic Cooperation and Development (OECD).Her research was reported in the Financial Times in its edition of 14 November 2011. - See more at here.

Most recently, her research on Jump detection has attracted wide interest from the U.S. regulators and practitioners from the industry. This work is presented in the Commodity Futures Trading Commission (CFTC), the Office of Financial Research (OFR) and International Monetary Fund (IMF). Other on-going projects Maggie collaborates with CFTC will potentially build up policy impact in the area of High Frequency Trading.

Since February 2016 I have also acted as Director of Internationals of the School of Mathematics. I have led the signing of MoU (Memorandum of Understanding) with four top universities in China, which guarantee 30 international students (at least 10 of whom are recruited onto Financial Mathematics). These are

  • Xiamen University (XMU): I obtained two mobility funds to facilitate collaboration at all levels including faculty research, joint PhDs and various u/g and p/g programs. I have signed agreements for 1+3 u/g program; 1+1 p/g program; 1+1+1 p/g program. These are expected to generate approximately good income flow and international students over 3 years.
  • Beijing Normal University (BNU): I signed an agreement for a 3+1 schemefor 3 years with good estimated income and international student numbers.
  • Beijing Normal university, Zhuhai (BNUZ): I signed a 2+2 for 3 years with with potential income and students.
  • Beijing University of Technology (BJUT): I signed an agreement on 1+1 at p/g level for 3 years.

I also chaired an EPSRC doctoral scholarship interview panel within the School of Mathematics and am a member of the School Board. Outside Cardiff, I am currently external examiner in finance at Bath University and at Plymouth University.
