Research interests

I am an Assistant Professor at the University of Southern Denmark. My primary interests are explaining and describing demographic patterns across the "tree of life". However, my research interests are varied and range from climate change, macroevolution and macroecology, to senescence and population dynamics.

Before my appointment at the University of Southern Denmark I spent a couple of years working on similar things as a research scientist at the Max Planck Institute for Demographic Research in Rostock, Germany. In addition, I spent some time working with Dr Jinliang Wang at the Institute of Zoology (London) on population genetics.

My first post-doc, based at Imperial College London, was on the LITS project, a database of UK-based long-term individual-based time series data sets.

Media

My paper in Nature on the "Diversity of ageing across the tree of life" has received a lot of media attention. One of the best write-ups I've seen in the popular science blogs was on the National Geographic blog, "Only Human".

Here's a few more of the many.


 I also featured the work in interviews with the Nature Podcast (starts at 14:48), on the BBC World Service, and Voice of Russia radio.

Our video about BaSTA - our Bayesian mortality inference package has been rather popular on YouTube.

BaSTA was also featured in the Methods in Ecology and Evolution blog.

  • R Function: remove unused factor levels in a data frame Sometimes it is necessary to drop the unused factor levels across an entire data frame. This function does that:dropall <- function(x){    isFac = NULL    for (i in 1:dim(x)[2]){isFac[i] = is.factor(x[ , i])}    for (i in 1:length(isFac)){        x[, i] = x[, i][ , drop = TRUE]        }    return(x)    }

  • R function: circular mean Circular means are useful if you are dealing with data that are inherently "circular" such as the day or month of the year, or direction. For example, imagine your data consists of the month in which an event occurs, and you want to report the average month. If you had 3 observations in December, and 3 in February, the average should be in January (1) whereas the more conventional arithmetic mean would tell you the answer was 7. The trick to dealing with this issue is to convert the data into radians, and do a bunch of trigonometry. This is how you might approach it in R: You have 3 observations in December (12), and 3 in February. m = c ...
