# Dr Layna Groen

### Biography

Layna undertook undergraduate studies at the University of Sydney, majoring in Pure Mathematics, with submajors in Physics, Geology and Applied Mathematics. She then undertook a Diploma of Education at the then Sydney Teachers College.

After teaching high school maths and science for three years, she commenced the Graduate Diploma in Operations Research, followed by a Masters of Applied Science in the same area at the University of Technology, Sydney.

Her interest in financial modeling then lead her to the University of New South Wales, where she completed a Masters of Commerce (Honours) in Finance.

She returned to the University of Technology, Sydney to complete her Doctor of Philosophy (2002), again in the area of financial modeling. For some years Layna was the Course Director/Program Leader for the Bachelor of Mathematics and Finance program, and at various times held the positions of Exemptions Coordinator and Elective Coordinator for the School of Mathematical Sciences. She is current the Academic Liaison Officer for her School and the Honours Coordinator.

She has held the position of Assistant Student Ombud, and later the Student Ombud, positions she held from 2004 to 2010. She was a Science Faculty Representative on Academic Board 2008-2012, and was a member of the Academic Administration Committee from 2008 to 2012. During this time she chaired working groups on Assessment Policy and Procedures and Admissions Policy and Procedures, and continues to work in the area of Rules review. She returned to the Academic Administration Committee in 2015 as the Deputy Chair.

### Professional

For many years, Layna has been involved with the Sydney Chapter of the Australian Society for Operations Research, and has held positions as Treasurer and Chair at various times. She was a member of the International Ombudsman Association during her time as a Student Ombud.

### Research Interests

Dr Groen has undertaken a small number of consulting projects in queueing theory and simulation, while her research interests focus on static and dynamic optimisation, including optimal control, and mathematical modeling.

She has worked on the optimal location of tsunami warning buoys in the Indian Ocean and the Mediterranean Sea. With her final year Operations Research class, she has constructed a multiple-objective goal programming model for water allocation in the Murrumbidgee catchment.

Layna is a Senior Lecturer with 25 years experience in the teaching of Operations Research at the undergraduate and postgraduate levels, and in the supervision of honours and postgraduate students.

She has taught the undergraduate subjects 35140 Introduction to Quantitative Management, 35241 Optimisation in Quantitative Management, and 35340 Quantitative Management Practice in the Faculty of Science as well as a number of postgraduate and honours level Operations Research subjects. This includes subjects in optimal control, stochastic programming and large scale mathematical programming. She has also lectured and tutored first year mathematics subjects for Engineering and Science students. One of her current research interests is first year preparedness for mathematics for STEM students. She has a long time interest in learning design and innovation in mathematics assessment.

She has also taught the postgraduate subject 21742 Quantitative Management for the Faculty of Business and continues to teach the current equivalent subject. She also teaches Project Management for postgraduate Science students.
