Chemical Engineering Option (ChE)

Caltech’s Chemical Engineering option prepares its students for the future, whether that be furthering research and development in industry, or continuing their studies at the graduate level. The option's breadth enables its students to make an impact in a variety of fields, such as: researching sustainable technologies (energy efficiency, pollution management, climate mitigation, biofuels); inventing novel biotechnologies (enzyme engineering, cell culturing, pharmaceuticals); and developing processes for organic (polymers, films, fuels, pharmaceuticals) and inorganic (semiconductors, ceramics) products.

This is accomplished through a mixture of interdisciplinary classes that expose students to: most fields of science (chemistry, physics, mathematics, biology); core chemical engineering principles; and an area of specialization. The inherently computational nature of chemical engineering shines through courses’ active use of computational software such as Python, Matlab, Mathematica and COMSOL for modelling and data analysis. At the same time, classes and independent projects also focus on systematic analysis and problem solving, incorporating social, economic, environmental, and technical constraints to tackle the open-ended challenges of today and tomorrow with new and creative solutions. Undergraduate research is emphasized, and students are encouraged, even in the first year, to participate in research with faculty.

First-year students normally take core courses in mathematics, physics, chemistry, and biology (Ma 1 abc, Ph 1 abc, Ch1 ab, Bi 1), as well as general chemistry lab (Ch3a or Ch 3x). First-year students may take ChE 15 or wait until their second year. In their second year, students take advanced courses in math and science, including differential equations (Ma 2), applied math (ACM 95 ab), wave physics (Ph 2a), organic chemistry (Ch 41 ab), and organic chemistry lab (Ch/ChE 9).

The option’s curriculum begins in students’ second year and continues through their third year with fundamental studies in heat transfer, fluid mechanics, mass transfer, thermodynamics, reactor design, and chemical kinetics. While still building a common foundational toolkit, third-year students also begin to specialize in one of five tracks: biomolecular, sustainability, process, materials, computational. Students learn and use design principles in multiple lab courses that entail hands-on, open-ended projects relevant to current research so students can innovatively apply chemical engineering concepts. Students may also pursue an undergraduate thesis to explore research topics under the mentorship of professor - proposing a research plan, applying relevant lab techniques, and presenting results through project reports, oral presentation, and written thesis.

Attention is called to the fact that any student whose gradepoint average is less than 1.9 at the end of an academic year in the subjects listed under the Division of Chemistry and Chemical Engineering may, at the discretion of the faculty in this division, be refused permission to continue the work in this option.

2. Completion of a track (biomolecular, sustainability, process systems, materials or computational), each consisting of at least 72 units of science or engineering courses. Students should inform the executive officer of their track choice by the beginning of the spring quarter of the sophomore year by providing a planned schedule for completion of all degree requirements. Requirements for the tracks are as follows.
   1. Biomolecular track: BE/ChE 163, Ch/Bi 110ab, [ChE 130 or ChE 90 c], and additional units of bioengineering or biochemical engineering electives or approved related courses.^3,4
   2. Sustainability track: two of [ChE/ESE/ME/MS 111, ESE 101, ESE 102, ESE 103], one of [ChE 128 ChE 90 c, Ge 114 a], and additional units of 100 level ESE electives, 100 level EST electives or approved related courses.^3,4,5
   3. Process systems track: ChE 118, ChE 120, [ChE 128 or
      ChE 90 c], and additional units of engineering electives,
      courses from the other tracks, or approved related
      courses.³
   4. Materials track: [ChE 128 or ChE 90 c]; one course on materials synthesis or processing selected from [Ch 102, Ch 117, Ch/ChE 147², ChE 115², or MS 133]; at least one course on the physical basis of structure and properties selected from [Ch 120, ChE/Ch 148², MS 115, MS/APh 122², MS 131, or MS 132]; and additional units of chemical engineering, materials science, or applied physics elective courses selected from [ChE/Ch 155², ChE/Ch164, ChE/Ch 165, APh/EE 109, APh 114 ab, any MS course]or approved related courses.^3,4
   5. Computational track: ACM/IDS 104, ChE 141, at least one course sequence from [Ch 121 ab; BE/ChE 163 & BE/CS/CNS/Bi 19a; ESE 101 & ESE 136; Ae 232 ab; or ChE 90 abc], and additional units from ChE 142 or approved courses in IDS, ACM, CS or related options.³
3. Passing grades must be earned in all courses required by the Institute and the option. None of the courses satisfying option requirements may be taken pass/fail (except when courses are only available P/F)
4. Passing grades must be earned in a total of 486 units, including courses listed above.

^† Ph 12 b may substitute for Ch 21 a; Ch 24 may substitute for Ch 21b.
¹ The 9 units of Ec 11 or BEM 103 partially satisfy the Institute requirements in humanities and social sciences. BEM 102 does NOT count for Institute core social science course.
² Course is not typically offered every academic year. Given in alternate years.
³ No more than 18 units of [ChE 90ab or ChE 80] may count as track electives.
⁴ ChE 118 and/or ChE 120 may be elected provided the design project undertaken contains a significant component relevant to the track.
⁵ students in the sustainability track are encouraged to take one policy-related course [BEM/Ec/ESE 119 or ME/EE/EST 117] as a track elective.
