Summary "Amines and their acylated derivatives – amides – are among the most common chemical functional groups found in modern pharmaceuticals. Despite this there are few methods for their efficient, environmentally sustainable production in enantiomerically pure form. This proposal seeks to provide new catalytic chemical methods including 1) the catalytic, enantioselective synthesis of peptides and 2) catalytic methods for the preparation of enantiopure nitrogen-containing heterocycles. The proposed work features innovative chemistry including novel reaction mechanism and catalysts. These methods have far reaching applications for the sustainable production of valuable compounds as well as fundamental science."

Project Describing Evolution with Theoretical, Empirical, and Computational Tools

Summary As evolutionary biologists we are of course motivated by the desire to gain further insight in to the evolution of natural populations. The main goals of this proposal are to (i) develop theory and methodology that will enable the identification of adaptively evolving genomic regions using polymorphism data, (ii) develop theory and methodology for the estimation of whole-genome rates of adaptive evolution, and (iii) apply the developed theory in two strategic collaborative applications. Capitalizing on recently available and soon-to-be available whole genome polymorphism data across multiple taxa, these approaches are expected to significantly improve the identification and localization of recent selective events, as well as provide long sought after information regarding the genomic distributions of selective effects. Additionally, through these on-going collaborations with empirical and experimental labs, this methodology will allow for specific hypothesis testing that will further illuminate classical examples of adaptation. Together, this proposal seeks to Describe Evolution with Theoretical, Empirical and Computational Tools (DETECT), seeking to accurately describe the very mode and tempo of Darwinian adaptation.

Project Heterogeneity That Matters for Trade and Welfare

Summary Accounting for firms' heterogeneity in trade patterns is probably one of the key innovations of international trade that occurred during the last decade. The impact of initial papers such as Melitz (2003) and Bernard and Jensen (1999) is so large in the field that it is considered to have introduced a new paradigm. Apart from providing a convincing framework for a set of empirical facts, the main motivation of this literature was that there are new gains to be expected from trade liberalization. Those come from a selection process, raising aggregate productivity through the reallocation of output among heterogeneous firms. It initially seemed that the information requirements for trade policy evaluations had become much more demanding, in particular requiring detailed micro data. However, the recent work of Arkolakis et al. (2011) suggests that two aggregate ``sufficient statistics'' may be all that is needed to compute the welfare changes associated with trade liberalization. More, they show that those statistics are the same when evaluating welfare changes in representative firm models. The project has three parts. The first one starts by showing that the sufficient statistics approach relies crucially on a specific distributional assumption on heterogeneity, the Pareto distribution. When distributed non-Pareto, heterogeneity does matter, i.e. aggregate statistics are not sufficient to evaluate welfare changes and predict trade patterns. The second part of the project specifies which type of firm-level heterogeneity matters. It shows how to identify which sectors are characterized by ``productivity sorting'' and in which ones ``quality sorting'' is more relevant. Extending the analysis to multiple product firms, the third part shows that heterogeneity inside the firm also matters for welfare changes following trade shocks. It considers how the change in the product mix of the firm following trade liberalization alters the measured productivity of the firm.

Project Live Tapings of Material Formation: Unravelling formation mechanisms in materials chemistry through Multimodal X-ray total scattering studies

Summary With this proposal, I want to develop a new, multimodal approach to in situ X-ray scattering studies to unravel formation mechanisms of the solid state. The aim of the project is to develop a unified view of metal oxide nucleation processes on the atomic scale: From precursor complexes over pre-nucelation clusters to the final crystalline particle.
The development of new materials relies on our understanding of the relation between material structure, properties and synthesis. While the intense focus on ‘materials by design’ have made it possible to predict the properties of many materials given an atomic arrangement, actually knowing how to synthesize it is a completely different story. Material synthesis methods are to a large degree developed by extensive parameter studies based on trial-and-error experiments. Specifically, our knowledge of particle nucleation is lacking, as even non-classical views on nucleation such as the concept of pre-nucleation clusters do not apply an atomistic view of the formation process. Here, I want to use new methods in X-ray total scattering and Pair Distribution Function analysis to follow nucleation processes to establish the framework needed for predictive material synthesis. One of the large challenges in studying nucleation is the lack of a characterization method that can give structural information on materials without long-range order. I have demonstrated that time-resolved X-ray total scattering gives new possibilities for following structural changes in a synthesis, and the use of total scattering has opened for a new view on material formation. However, the complexity of the structures involved in nucleation processes is too large to obtain sufficient information from X-ray total scattering alone. Here, I will combine X-ray total scattering data with complementary techniques using a new multimodal approach for complex modelling analysis, providing a unifying view on material nucleation.
