Dark Energy Spectroscopic Instrument has already started taking commissioning data. Using a 4-meter Mayall telescope in Arizona, it will observe redshifts of 50 million distant galaxies, and will use sophisticated statistical techniques to measure properties of the Universe.

With first science papers coming out in early 2023 we are hoping to crack the mystery of dark energy and dark matter.

I am currently a co-chair of the galaxy and quasar clustering working group for DESI. In the past, I have led work on deriving strategy for systematic errors, and forecasting DESI scientific yield for different survey strategies.

DESI is funded by the Department of Energy and participating institutions.

Euclid - a 1.5-meter space telescope - will be launched to space in 2022. It will be observing spacial distribution of emission line galaxies over a wide redshift range over five years.

The science goal of Euclid is pretty similar to that of DESI, use statistical properties of galaxy distribution to measure properties of dark energy and dark matter.

I am currently leading the development of the sample selection processing function for Euclid. In the past, I have led the galaxy clustering working group, and the observational systematics work package.

Euclid is a 600 billion euro project funded by the European Space Agency.

Nancy Grace Roman space telescope is a highly anticipated space mission currently under development. This 2.4-meter telescope will have the same resolution as the Hubble space telescope with 100 times the field of view.

Roman has a lot of similarities with Euclid. It will have better instruments and will potentially go to higher redshifts over 2,000 square degrees of the sky, providing very important weak lensing and galaxy clustering measurements.

I am part of the Roman Science Investigation Team working on the dark energy side of the experiment.

Roman is funded by NASA and is a flagship mission on par with the Hubble and the James Webb space telescopes.

ATLAS is a proposed space mission that plans to use a 1.5-meter telescope to follow up Roman targets and measure redshifts of 200 million galaxies up to z < 7.

ATLAS has multiple science objectives, including galaxy evolution, Milky Way science, Kuiper belt of the solar system, and cosmology.

I am involved in studying cosmology part of the ATLAS mission, investigating the ways in which optimal cosmological information about dark energy can be derived.

We are hoping that ATLAS will officially be selected by NASA to launch in 2030.
