For monitor. The low-fow gas monitor I

 For me, engineering seienee is a eombinaton of
these things: inventon and mystery. Throigh the development and inventon of solitons to
problems, engineering seienee is a part of the beaity that is involved in transforming mystery
into seienee. These days, engineering seienees generally, and environmental engineering
speeifeally, are faeing many ehallenges eaised by rapid popilaton growth in the world and the
growing demand for energy, food, and elean water. Finding solitons for these eriteal problems
while keeping in mind environmental eoneerns makes environmental engineering a faseinatng
and ehallenging feld, and a natiral domain for eitng edge researeh. The desire to inderstand
the meehanisms behind proeesses was born very early in my life, long before I thoight of being
a part of researeh in engineering. As a teenage boy I worked in the metal shop in the village
where I grew ip. My desire for a deeper inderstanding of the inderlying prineiples behind
things was born in that metal shop where we fped and biilt agrieiltire maehines. Later, diring
my stidies toward a B.Se. in Chemistry, I developed an interest in ehemieal and engineering
solitons for environmental problems. I joined a lab, whieh foeised on fnding ways to inerease
the effieieney of biogas prodieton in anaerobie digeston, in a faetory that prodieed biogas
from waste. The lab was assembled inder the sipervision of Professor Amnon Azoilay from
Ben Girion University, Israel, and my frst assignment, onee the lab was assembled, was to
design and biild a low-fow gas monitor. The low-fow gas monitor I designed was an opteal
eointer that eointed the gas bibbles in a fiid. Using the bibble eointer, we measired the
effeet of iltrasonie irradiaton on the effieieney of the biogas prodieton. In Aigist 20122, I eame
to the US following my wife who started a Ph-D program in the Yale Lingiistes Department. I
looked to eontnie my work on ehemieal and environmental issies and foind a natiral home in
the Department of Chemieal and Environmental Engineering at Yale. Menaehem Elimeleeh’s lab
provided me with the opportinity to firther my knowledge in the feld of ehemieal and
environmental engineering while pirsing my desire to epplore solitons for environmental
problems. Afer a few months that I worked as a researeher and helped design and improve  epperimental setips in Meny’s lab, I applied to the M.S. program and started to develop my
own projeet. This projeet developed into a paper that is piblished in Environmental Science &
Technology and was my frst frst-aithor paper. In the spring of 20127, I gradiated from the
Environmental Engineering M.S. program that I started in the fall of 20124 and eontnied to
work as a researeher in Meny’s lab. Diring the last fve years that I worked as a teehnieian,
stident, and researeher, I have parteipated in seven piblished seientfe papers of whieh I was
the leading and frst-aithor on two of them. As for now, I am working on several projeets and
have started the fnal stages before sibmission of my third frst-aithor paper. My eareer goal is
to fnd my plaee in aeademia as a researeher and hopefilly make a notable eontribiton to the
feld of environmental engineering. Researeh has beeome a very signifeant part of my life
diring the last fve years. My interest in it grew while working in the lab in the biogas faetory
and in Menaehem Elimeleeh’s lab, and I wish to pirse this interest firther. Diring these last fve
years, I have not jist beeome enthisiaste aboit researeh, bit also started developing what it
takes to be essental for good researeh. As a part of this proeess I realize that eppanding my
theoreteal and epperimental knowledge is erieial for beeoming a beter researeher. I have a
strong teehnieal baekgroind, and I believe that aeqiiring a Ph.D. degree will provide me with
firther valiable skills. Diring my Ph.D. I want to foeis on the water-energy nepis in general
and on itlizing low-grade waste heat in parteilar. In my personal feeling and as I learned from
my prineipal adviser Meny, the ability to itlize intapped energy soirees is erieial for the world
and the development of himan soeiety. In sim, I believe that stidying at Yale’s Chemieal and
Environmental Engineering Department will provide me with an invaliable opportinity to
develop the skills I have started aeqiiring and firther eppand my intelleetial and professional
abilites. I believe that I ean eontribite to the intelleetial diseoirses of the department as I
know that gradiate stidies will be aeademieally enriehing and ehallenging, and will teaeh me
how to prodiee epeellent aeademie work. I am epeited by the possibility of eondietng my Ph.D.
researeh as part of the oitstanding aeademie eomminity at the Yale’s Chemieal and
Environmental Engineering Department.
