In this paper we trained ideal observer models to estimate 3D motion from naturalistic binocular video clips. We show that the resulting ideal observer exhibit non-obvious behaviors that are similar to those reported in human psychophysics.

In this paper we did a systematic meta-analysis of the SARS-CoV-2 serological literature to collect a dataset on how assay sensitivity changes with time after infection. We report that assay characterisics are an essential determinant of sensitivity dynamics, and discuss the potential biases that this introduces in the literature.

In this paper we modeled the interaction between non-pharmaceutical interventions for SARS-CoV-2 (e.g. contact tracing) and the number of infected individuals in a population. We find connections between the resulting dynamics and the Allee effect from ecology, and discuss the implications for epidemic management.

In this paper, COVID-19 fatality is assessed in developing countries using the golden standard of seroprevalence studies meta-analysis. We find that the infection fatality rate is roughly 2 times higher than in high-income countries. This paper was featured in Nature News, Forbes, Quartz, and other news media.

In this paper we report the age-stratified proportion of SARS-CoV-2 infections that result in severe and critical disease. For this we use the gold standard of serological survey meta-analysis, and collected a unique dataset on hospitalizations and ICU admissions from publich health authorities around the world. We show that the risk of severe and critical disease increases exponentially with age, but much less steeply than the risk of fatal illness. This work has been cited in media outlets and in a United States House of Representatives hearing about school policies during COVID-19.

In this paper we elaborate on out previous psychophysical findings that higher-order texture statistics are a secondary segmentation cue for humans, compared to spectral statistics. We analyze the contribution of both types of statistics to a natural image segmentation task and find that higher-order statistics are redundant with spectral statistics. We argue that this might explain their secondary role in human perception.

In this paper we use psychophysics experiments with Portilla-Simoncelli textures to show that texture segmentation affects contextual modulation in peripheral vision. This flexible contextual modulation cannot be accounted for by popular pooling models of crowding. We probe the relevance of different texture properties to contextual modulation, providing guidance for studying the neural mechanisms of flexible contextual modulation.

Tyrosine nitration is an oxidative post-translational modification that can occur in proteins associated to hydrophobic bio-structures such as membranes and lipoproteins. In this work, we studied tyrosine nitration in membranes using a model system consisting of liposomes with pre-incorporated tyrosine-containing 23 amino acid transmembrane peptides.
