In this statement of purpose sample, the applicant communicated clear focus and direction while remaining flexible in terms of academic pursuits and long-term career plans. The essay’s technical nature is perfectly appropriate for application to a graduate program in the natural sciences.
While my undergraduate and Master’s curriculum have provided exposure to a wide variety of environmental engineering topics, I have gained extensive knowledge in relatively few areas. I have, however, found an area in which my curiosity and my ability are suitably paired. As an M.S. student I have held a research assistantship position for the last year and a half, working both at the university and at a national laboratory. The strengths of the Civil (Environmental) Engineering Department at the university, as well as those of the group at the laboratory, lie in the investigation of the fate and transport of subsurface contaminants, along with general groundwater quality and flow characteristics, and it is also within these areas that my research interests reside.
[Here the applicant describes his specific research experience.]
Although my strengths are concentrated in these areas, my curiosity is by no means limited to these topics. I believe that I have a solid foundation, but through a program of graduate study and research I hope to develop expertise in these and other related areas. One such area of interest is the remediation of contaminated groundwater and contaminant plumes by incorporating microbial processes with in situ treatment techniques. I also find the interdisciplinary relationship between environmental engineering and ecology to be of great personal interest. One particular example is the growing trend toward identifying and controlling diffuse source contamination from areas of heavy agricultural activity. The processes involved in this contamination, as well as the resultant heavy down-gradient nutrient loadings, play an extensive role in the ecological development of receiving waters and need to be understood more comprehensively. The curriculum in the Environmental Engineering Program, particularly through interactions involving the Studies in Physical & Chemical Hydrogeology program, provides an opportunity to expand my knowledge in these areas while pursuing my ambitions in the area of subterranean contaminant transport processes. Further, your graduate program would permit me to incorporate my areas of interest into an applied research project under the mentorship of the faculty in the Department of Civil and Environmental Engineering.
Ultimately, I aim to gain a faculty position at a university and to continue my involvement in innovative research in the field while directly encouraging the development of aspiring engineers, both in the classroom and laboratory. In this manner I believe I can make a significant and purposeful contribution to the scientific community while gaining a great deal of personal satisfaction.
