My primary interest in to understand our universe by measuring the four-dimensional ripples on the spacetime fabric (aka **Gravitational Waves**). I work on the **LIGO experiment** which detected these waves after 100 years since Einstein first predicted in 1915. Our first gravitational wave detection came from collision of **Black Holes, **which also nicely matched with my supercomputer simulations. My current research is to hunt for gravitaitonal waves from massive black holes that may have formed from the very first stars in our universe.** **On other days, I probe the interface of Science & Technology with **National Security** strategies.* *Apart from the mysteries of our universe, I deeply care about Student Affairs and** Education Policy **at all levels: from K-12 schools to universities.

Project

As a fellow at one of the LIGO experiments in Louisiana (pics), I work on classifying instrumental glitches which hurts our ability to detect astrophysical gravitational waves. I "inject fake gravitaitonal waves" in LIGO to comprehend our end-to-end readiness for extracting astrophysics. The third LIGO detector is all set to be constructed in India by 2023, and I actively collaborate with universities in India to built human capital for this mega-science experiment. I am also investigating orbital dynamics of space-based gravitational experiments like, LISA and science cases for next-generation gravitaitonal wave experiments.

By conducting supercomputer simulations of Einstein's Equations, I analyze the dynamics of black holes in strong gravity. My simulations (pic at top) are directly utilized to find gravitational waves from massive black hole collision (50-1000 solar masses) for experiments like LIGO. My recent focus has been to hunt for intermediate mass black holes in the gravitational wave band. I use transient gravitaitonal wave searches to find these massive black hole in Advance LIGO detectors.

As a Sam Nunn Fellow on National Security at the School of International Affairs at Georgia Tech, I investigated the interface of science and technology with national security policy. I conducted two independent research in this area: (i) impact of big data sciences on intelligence gathering, and (ii) interplay of space-science with diplomacy and national security goals.

I serve as the Vice-President of the Graduate Student Body at Georgia Institute of Technology and contribute in various institutional policy reforms. I also collaborate with three K-12 schools in India to enhance their science, mathematics and computer education. In my efforts to enhance space-science research in India, I serve as an advisor to the space club in M.S. University, Baroda.

**K. Jani **et al (*Special Issue Article, Classical & Quantum Gravity*)

- The catalog consists of 452 distinct waveforms from more than 600 binary black hole simulations.

- The role of the catalog in interpreting the GW150914 event and future massive binary black-hole search in LIGO is discussed.

**K. Jani **(arXiv 1610.08618 , Submitted to Space Policy Journal)

- I devise a framework to quantify the impact of international collaborations in achieving the space-science goals as well as in enhancing the key sectors of development of a nation.

- My study concludes that international cooperation in space can significantly enhance scope of science goals, but has relatively little return of investment towards science education and national security.

K. Jani (arXiv 1610.08629, submitted to DRDO Journal)

- My study focuses on the inherent limitations of big data, which affects the intelligence agencies from gathering of information to anticipating surprises.

- I narrate some of the ongoing work in nuclear intelligence using simple analytics and argue on why big data analysis in that case would lead to unnecessary complications

**K. Jani**, L. S. Finn, M. J. Benacquista (arXiv 1306.3253)

- Once LISA's satellites are placed in their orbits, the orientation of the interferometers at any future time is fixed by Kepler's Laws based on the initial orientation of the spacecraft constellation, which may be freely chosen

- By artful choice of the initial orientation, we can choose to optimize or suppress the antennas sensitivity to sources whose location may be known in advance (e.g., the Galactic Center or globular clusters).

- On September 14, 2015 at 09:50:45 UTC the two detectors of LIGO simultaneously observed a transient gravitational-wave signal.

- This is the first direct detection of gravitational waves and the first observation of a binary black hole merger.

**K. Jani **as part of LIGO Scientific Collaboration

- The signal, GW151226, was observed by the twin detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO) on December 26, 2015.

- This second gravitational-wave observation provides improved constraints on stellar populations and on deviations from general relativity.

**K. Jani** as part of LIGO Scientific Collaboration

- We describe the analyses that first detected GW150914 as well as the parameter estimation and waveform reconstruction techniques that initially identified GW150914 as the merger of two black holes.

- We find that the reconstructed waveform is consistent with the signal from a binary black hole merger with a chirp mass of ∼30 M⊙ and a total mass before merger of ∼70 M⊙ in the detector frame.

**K. Jani **as part of LIGO Scientific Collaboration

- We compare GW150914 directly to simulations of coalescing binary black holes in full general relativity, including several performed specifically to reproduce this event.

- Our calculations go beyond existing semianalytic models, because for all simulations, we perform comparisons which account for all the spin-weighted quadrupolar modes
