Work assignments 

The project's contribution will lie at the intersection of random matrix theory and statistical inference theory, with applications in several fields of science. Special emphasis will be devoted to practical problems in economics and finance, like the construction of high-dimensional optimal portfolios.

Motivated by the widespread application of sample generalized inverses in practice when the dimension of the data-generating process exceeds the sample size, this project will contribute by developing the distributional properties of generalized inverses of the high-dimensional sample covariance matrix. The project's findings will yield improved estimators of high-dimensional quantities by developing new linear and nonlinear shrinkage approaches. In particular, new estimators of optimal portfolio weights will be derived, leading to considerably more stable and less risky trading strategies.

For this position, we are seeking a highly qualified postdoctoral researcher who will contribute substantially to the quantitative research carried out in the division in collaboration with national and international partners.

As postdoc, you will principally carry out research. A certain amount of teaching may be part of your duties, up to a maximum of 20% of working hours.

Qualifications

To be qualified to take employment as postdoc, you must have been awarded a doctoral degree or have a foreign degree that is deemed to be equivalent to a doctoral degree. This degree must have been awarded at the latest by the point at which LiU makes its decision to employ you.

We are seeking a candidate who holds a PhD in a quantitative discipline such as mathematics, statistics, or a related field, with applications in finance or economics. Candidates will be evaluated based on their publication record and their active participation in international conferences relevant to the position. Publications in leading international journals in statistics, econometrics, and finance will be considered a strong merit.

Particular consideration will be given to candidates who have demonstrated the ability to conduct high-quality research in high-dimensional statistical theory, from both theoretical and applied perspectives. Strong programming skills in R, MATLAB, and Python are highly desirable.

The successful candidate is expected to be fluent in English and open to both national and international research collaboration related to the position. Knowledge of Swedish is considered meritorious but is not a requirement. 

It is considered advantageous if your doctoral degree is no older than three years at application deadline for this job. If there are special reasons for having an older doctoral degree – such as taking statutory leave – then these may be taken into consideration.
