The lensing collaborations teamed up for the first joint cosmological analysis and I played a a leading role in the effort. We did an extensive mock analysis to disentangle our different analysis choices and formulate a Hybrid pipeline that was suitable for the joint statistical power - a valuable stepping stone toward analyses with Rubin data.

We reviewed the evidence for a tension in the value of S8 between Planck CMB and other cosmological observations. We argue that any discrepancy may be a caused by uncertainties in the theoretical predictions arising from the modelling of the mass fluctuations on non-linear scales, either due to baryonic feedback or non-standard dark matte
We reviewed the evidence for a tension in the value of S8 between Planck CMB and other cosmological observations. We argue that any discrepancy may be a caused by uncertainties in the theoretical predictions arising from the modelling of the mass fluctuations on non-linear scales, either due to baryonic feedback or non-standard dark matter. . If our proposed explanation of the S8 tension is correct, the required suppression must extend into the mildly non-linear regime to k~0.2h/Mpc [Amon and Efstathiou 2022; Preston et al 2023].
We present new measurements of the excess surface mass density profiles using the three state-of-the-art lensing surveys (DES, HSC, KiDS) and jointly analyse with BOSS galaxy clustering to assess their consistency on small and large-scales [Amon and Robertson et al 2022].
I co-pioneered the Lensing Without Borders cross-survey collaboration to test the consistency of weak lensing results [Amon+2017; Leauthaud & Amon+2021]
I was part of a small team preparing a note recommending target fields for commissioning, on behalf of the Dark Energy Science Collaboration .
Dark Energy Survey Year 3 Cosmology from Weak Lensing and Clustering 3x2pt: I played a pivotal role in the Dark Energy Survey Year 3 combined lensing and clustering cosmology analysis, leading the weak lensing results and coordinating three analysis teams to the most precise cosmological constraints of its kind [DES Collaboration 2021].
Dark Energy Survey Year 3 Cosmology from Cosmic Shear: I led and coordinated the Dark Energy Survey Year 3 cosmic shear lensing analysis using the most powerful data until present, of 100 million galaxies [Amon et al 2021].
Dark Energy Survey Deep Fields: I co-coordinated this team, responsible for the processing and validation of the deep, optical+NIR fields, crucial for the Year 3 analysis. 
I used machine learning and data science techniques to develop new statistical methods for accurate weak lensing measurements, especially for estimating and calibrating photometric redshifts for the Dark Energy Survey [15, 14].
I have worked on validating the Dark Energy Survey's Year 3 galaxy catalogue. Specifically, I tested the shape calibration, point spread function modelling and using image simulations to understand blending, and co-coordinated the shear testing team [11,12,13].
I performed a combined-probe test of General Relativity with weak lensing and spectroscopic data to measure the E_G statistic [Amon+2018]
I processed and analysed the bright-time, single i-band dataset from the KiDS survey, which already spanned >1000 sq. deg. in 2018. I tested the homogeneity of the survey, measured and validated the PSF, shears and redshift distributions and used it as a consistency test of the main KiDS data [Amon, Heymans et al 2017]
