Matthew Low
I am an ecologist and a veterinarian with a special interest in disease ecology and the factors regulating animal populations. I study this by using advanced statistical modelling approaches to identify long-term trends, disease patterns and the processes driving population changes. I also work closely with students to design courses that inspire them and provide the skills they need to be successful scientists and life-science professionals

Presentation

My research background is diverse and spans veterinary epidemiology, population ecology, behavioural ecology, life-history evolution and statistical methods. For this, much of my research has been based on long-term monitored population systems with detailed individual-level data (e.g. stitchbirds, domestic cats, penguins, wolverine, honeybees, snow leopards and house crickets).

Most of my research can be broadly categorised into: (1) the factors regulating the growth and structure of animal populations, and (2) using advanced statistical methods to understand causality, data collection biases and hidden ecological processes. Together, these complementary research fields enable me to work on a number of exciting epidemiological questions in wild and domestic species, including:

- Using state-space reconstruction to determine the causal drivers of Puumala orthohantavirus (PUUV) infection in bank voles and people

- Population patterns of feline hip dysplasia in domestic cats: its heritability, genetic correlations with body type and response to selective breeding

- Impacts of viral diseases on survival and fecundity in house crickets reared for the insects-as-food industry: can disease management improve sustainability?

- The effect of observer bias in snow leopard monitoring and the development of a disease monitoring network in High Asia

- Accounting for detection and observer bias in Malarial mosquito surveys

- The impact of disease and hive management on honey bee health 

- Long-term trends of seabirds on the Great Barrier Reef: patterns and causes

- The impact of forestry management on biodiversity and simple solutions to maintain biodiversity in multiple taxa 

 

Because of the uncertainties inherent in these systems and data collection processes, one of the overriding goals in my work is to properly account for this uncertainty and to provide accurate probabilistic measures of risk or treatment effects. For this I generally use a Bayesian Hierarchical modelling approach. This provides greater flexibility in modelling the factors of interest while producing probabilistic statements on the predictions from the model. This is ideal for communicating precise estimates of uncertainty to the scientific and non-scientific community. I also teach these methods to post-graduate students.

Teaching

In my teaching I work closely with the students to deliver courses that are not only relevant and applicable to their interests and skills development, but also create a working atmosphere that is co-operative and enjoyable. Because different students have different needs, the structure of my courses allows for students to work to their own capacity and gives them the support they need to ultimately succeed.

Postgraduate education

I have developed two PhD level courses that I teach each year through the SLU research schools. These courses were designed to fill a gap in the teaching of modern statistical programming and modelling skills to post-graduate researchers

Programming in R

This 1-week intensive course teaches our young researchers how to use R to fit their specific research questions by teaching R as a language. This gives them the programming flexibility they need to work in this modern statistical platform.

Bayesian Hierarchical Modelling (for beginners and beyond)

This 2-week intensive course takes students from understanding the fundamentals of Bayesian methods right through to being able to implement Hierarchical models of any design they choose. The emphasis is teaching students flexible methods to handle the questions they want to ask of their data.

Undergraduate education

Because of my background in veterinary science, domestic animal behaviour & welfare, ecology and evolution, I also have developed and teach a cross-disciplinary undergraduate course for students studying animal science and ecology : 

Principles of Zoology, Evolution and the Natural History of Domestic Animals

In this course I focus on key aspects of the ecology and evolution of companion and common farm animals that are important for people working in domestic animal science fields, including veterinarians and animal technicians. The course is based around a general and intuitive understanding of these principles with a clear demonstration of their practical application.

Mentoring younger researchers

I also work with young researchers in Sweden, Africa and Nepal to help them develop their skills in scientific writing, applying for grant funding and statistical analyses.

Cooperation

I collaborate with many research groups within the university, and researchers, government stakeholders and NGOs from all over the world. These include the honeybee disease research group, the small mammal zoonoses research group and the sustainable insects-as-food research group at SLU. Internationally I work with the Snow Leopard Trust in Mongolia & India, the Great Barrier Reef Marine Park Authority in Australia, Makarere University in Uganda, the National Trust for Nature Conservation in Nepal, the Depatment of Conservation in New Zealand and the Australian Antarctic Division in Australia & Antarctica.

Background

My undergraduate and professional background is in veterinary science and applied animal behaviour (1988-1998 University of Queensland & Kessels Rd Veterinary Hospital). I worked in clinical veterinary practice for 5 years where I developed my skills in avian and wildlife medicine, applied animal behaviour therapy and small animal internal medicine.

From 1999-2004 I worked as a field biologist, veterinary consultant and PhD researcher in New Zealand on endangered bird species (Department of Conservation & Massey University). During ths time I helped develop national protocols for disease management for a number of species conservation programmes (stitchbird and kakapo).

From 2005-2007 I worked in Antarctica as a researcher testing new methods for surveying Adelie penguins (Australian Antarctic Division) as part of an international monitoring effort examining the impact of fishing in the Southern Ocean.

Since 2007 I have been working as a researcher at SLU on various projects related to population ecology, epidemiology and statistical methodology 

Supervision

I work with many MSc and PhD students across departments and faculties in providing support for their development in key skills areas: writing and structuring manuscripts, statistics and R programming. In an official capactity I have supervised 5 PhD students to completion.
