Clarification about the pronunciation of my name:
The following is how my name is written in the Devnagari script of my mother tongue Hindi:     क्षितिज कुलश्रेष्ठ
A transliteration of my name in the International Phonetic Alphabet:     kʃɪʈɪʤ kʊlʃreçtʰ
(If you can't see the above Unicode characters then you need to install Unicode Fonts.)
Nach mehrere Versuche zu erklären, wie mein Name ausgesprochen werden sollte, ist hier eine Annährung nach deutscher Phonetikregel:     "Kschittidsch Kullschrächth"
Sie könnten auch hören, wie ich meinen Namen ausspreche. You could also hear the way I pronounce my name.
Academic Career:

I received my Masters Degree from Indian Institute of Technology, Delhi, India, in Mathematics and Computing in August 2003. I was at TU-Dresden for the summer from May till the middle of July 2002 to work on Performance analysis and Optimisation on Parallel FEM Codes.

I implemented a Parallel Mixed Finite Element Method for solving clamped Anisotropic plate bending problems, which is a generalisation of the Hellan Hermann Miyoshi method for Biharmonic PDE. This was implemented on a machine developed in India called PARAM 10000 using MPI. This machine is a 8 SPARC processor machine with a special intercommunication system developed by C-DAC in Pune, India called KSHIPRA. I ported the code onto the Origin 2000, Origin 3800 and Cray T3E in ZHR and then optimised the performance of the code by using improved algorithms. I used direct factorisation to solve the linear system formed.

I was at Technische Universität Dresden from September 2003 working on Iterative Solution methods for the Anisotropic plate bending problem using another Mixed Finite Element method, which reduces to the Hellan Hermann Johnson scheme for the Biharmonic PDE.

Early in 2004 I started to research Quadratic Eigenvalue problems arising in external field Acoustics in association with Prof. Andreas Griewank and got interested in the field of Shape Optimisation.

I joined HU Berlin as a doctoral student in October 2004 and started on my PhD Project in April 2005. My work dealt with Structural and Topological Optimisation. The PhD-Defense took place on October 4, 2010.

I have also contributed to the MATHEON Project on General purpose, Linearly Invariant Algorithm for Large-Scale Nonlinear Programming and I am a co-author of the El-Rambo software package currently under development in this project.

Since June 2010 I am working with Prof. Dr. Andrea Walther in Paderborn on various aspects of her Algorithmic Differentiation package ADOL-C. My official homepage is here.

My other interests lie in the fields of:
